         * clashing], which can potentially be used in an attack, this contract uses the
         * https://blog.openzeppelin.com/the-transparent-proxy-pattern/[transparent proxy pattern]. This pattern implies two
         * things that go hand in hand:
         *
         * 1. If any account other than the admin calls the proxy, the call will be forwarded to the implementation, even if
         * that call matches one of the admin functions exposed by the proxy itself.
         * 2. If the admin calls the proxy, it can access the admin functions, but its calls will never be forwarded to the
         * implementation. If the admin tries to call a function on the implementation it will fail with an error that says
         * "admin cannot fallback to proxy target".
         *
         * These properties mean that the admin account can only be used for admin actions like upgrading the proxy or changing
         * the admin, so it's best if it's a dedicated account that is not used for anything else. This will avoid headaches due
         * to sudden errors when trying to call a function from the proxy implementation.
         *
         * Our recommendation is for the dedicated account to be an instance of the {ProxyAdmin} contract. If set up this way,
         * you should think of the `ProxyAdmin` instance as the real administrative interface of your proxy.
         *
         * NOTE: The real interface of this proxy is that defined in `ITransparentUpgradeableProxy`. This contract does not
         * inherit from that interface, and instead the admin functions are implicitly implemented using a custom dispatch
         * mechanism in `_fallback`. Consequently, the compiler will not produce an ABI for this contract. This is necessary to
         * fully implement transparency without decoding reverts caused by selector clashes between the proxy and the
         * implementation.
         *
         * WARNING: It is not recommended to extend this contract to add additional external functions. If you do so, the compiler
         * will not check that there are no selector conflicts, due to the note above. A selector clash between any new function
         * and the functions declared in {ITransparentUpgradeableProxy} will be resolved in favor of the new one. This could
         * render the admin operations inaccessible, which could prevent upgradeability. Transparency may also be compromised.

         * @dev Contract module that allows children to implement role-based access
         * control mechanisms. This is a lightweight version that doesn't allow enumerating role
         * members except through off-chain means by accessing the contract event logs. Some
         * applications may benefit from on-chain enumerability, for those cases see
         * {AccessControlEnumerable}.
         *
         * Roles are referred to by their `bytes32` identifier. These should be exposed
         * in the external API and be unique. The best way to achieve this is by
         * using `public constant` hash digests:
         *
         * ```
         * bytes32 public constant MY_ROLE = keccak256("MY_ROLE");
         * ```
         *
         * Roles can be used to represent a set of permissions. To restrict access to a
         * function call, use {hasRole}:
         *
         * ```
         * function foo() public {
         *     require(hasRole(MY_ROLE, msg.sender));
         *     ...
         * }
         * ```
         *
         * Roles can be granted and revoked dynamically via the {grantRole} and
         * {revokeRole} functions. Each role has an associated admin role, and only
         * accounts that have a role's admin role can call {grantRole} and {revokeRole}.
         *
         * By default, the admin role for all roles is `DEFAULT_ADMIN_ROLE`, which means
         * that only accounts with this role will be able to grant or revoke other
         * roles. More complex role relationships can be created by using
         * {_setRoleAdmin}.
         *
         * WARNING: The `DEFAULT_ADMIN_ROLE` is also its own admin: it has permission to
         * grant and revoke this role. Extra precautions should be taken to secure
         * accounts that have been granted it.

        /**
         * @dev This is a base contract to aid in writing upgradeable contracts, or any kind of contract that will be deployed
         * behind a proxy. Since proxied contracts do not make use of a constructor, it's common to move constructor logic to an
         * external initializer function, usually called `initialize`. It then becomes necessary to protect this initializer
         * function so it can only be called once. The {initializer} modifier provided by this contract will have this effect.
         *
         * The initialization functions use a version number. Once a version number is used, it is consumed and cannot be
         * reused. This mechanism prevents re-execution of each "step" but allows the creation of new initialization steps in
         * case an upgrade adds a module that needs to be initialized.
         *
         * For example:
         *
         * [.hljs-theme-light.nopadding]
         * ```
         * contract MyToken is ERC20Upgradeable {
         *     function initialize() initializer public {
         *         __ERC20_init("MyToken", "MTK");
         *     }
         * }
         * contract MyTokenV2 is MyToken, ERC20PermitUpgradeable {
         *     function initializeV2() reinitializer(2) public {
         *         __ERC20Permit_init("MyToken");
         *     }
         * }
         * ```
         *
         * TIP: To avoid leaving the proxy in an uninitialized state, the initializer function should be called as early as
         * possible by providing the encoded function call as the `_data` argument to {ERC1967Proxy-constructor}.
         *
         * CAUTION: When used with inheritance, manual care must be taken to not invoke a parent initializer twice, or to ensure
         * that all initializers are idempotent. This is not verified automatically as constructors are by Solidity.
         *
         * [CAUTION]
         * ====
         * Avoid leaving a contract uninitialized.
         *
         * An uninitialized contract can be taken over by an attacker. This applies to both a proxy and its implementation
         * contract, which may impact the proxy. To prevent the implementation contract from being used, you should invoke
         * the {_disableInitializers} function in the constructor to automatically lock it when it is deployed:
         *
         * [.hljs-theme-light.nopadding]
         * ```
         * /// @custom:oz-upgrades-unsafe-allow constructor

         *     _disableInitializers();
