Implement Storage Gap in Delegatable Contract

Description

If additional variables are added to the Delegatable contract, conflicts may arise with the storage slots previously written on the proxy.

Recommendation

To mitigate this issue, insert a storage gap in the contract:

abstract contract Delegatable is IDelegatable {
    mapping(address => address) public delegations;
    address private senderOverride;
    @>
    uint256[49] __gap;
    // *** code ***
