incorrect permit signature for version other than "1"

[0f0crypto]

The generated permit is incorrect when EIP712 is instantiated with any version other than "1" because the value is hardcoded in the gerDomain method https://github.com/dmihal/eth-permit/blob/34f3fb59f0e32d8c19933184f5a7121ee125d0a5/src/eth-permit.ts#L97

For example, the current version of the USDC token on Ethereum uses version "2"

    function initializeV2(string calldata newName) external {
        // solhint-disable-next-line reason-string
        require(initialized && _initializedVersion == 0);
        name = newName;
        DOMAIN_SEPARATOR = EIP712.makeDomainSeparator(newName, "2");
        _initializedVersion = 1;
    }

Therefore, using the signERC2612Permit does not work for USDC, i.e. called permit() reverts with EIP2612: invalid signature

Oh nevermind. I see the key is to use a domain object instead of the address as the second parameter 🤦
