     * To avoid https://medium.com/nomic-labs-blog/malicious-backdoors-in-ethereum-proxies-62629adf3357[proxy selector
     * 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 the {ITransparentUpgradeableProxy-upgradeToAndCall} function exposed by the proxy itself.
     * 2. If the admin calls the proxy, it can call the `upgradeToAndCall` function but any other call won't be forwarded to
     * the implementation. If the admin tries to call a function on the implementation it will fail with an error indicating
     * the proxy admin cannot fallback to the target implementation.
     *
     * These properties mean that the admin account can only be used for upgrading the proxy, 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. For this reason, the proxy deploys an instance of {ProxyAdmin} and
     * allows upgrades only if they come through it. You should think of the `ProxyAdmin` instance as the administrative
     * interface of the proxy, including the ability to change who can trigger upgrades by transferring ownership.
     *
     * NOTE: The real interface of this proxy is that defined in `ITransparentUpgradeableProxy`. This contract does not
     * inherit from that interface, and instead `upgradeToAndCall` is 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.
     *
     * NOTE: This proxy does not inherit from {Context} deliberately. The {ProxyAdmin} of this contract won't send a
     * meta-transaction in any way, and any other meta-transaction setup should be made in the implementation contract.
     *
     * IMPORTANT: This contract avoids unnecessary storage reads by setting the admin only during construction as an
     * immutable variable, preventing any changes thereafter. However, the admin slot defined in ERC-1967 can still be
     * overwritten by the implementation logic pointed to by this proxy. In such cases, the contract may end up in an
     * undesirable state where the admin slot is different from the actual admin.
     *
     * 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 `upgradeToAndCall` function inaccessible, preventing upgradeability and compromising transparency.

    /**
     * @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]
     * ```solidity
     * 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
     * constructor() {
     *     _disableInitializers();
     * }
