I think it could be better instead of check the [`DOMAIN_SEPARATOR` ](https://github.com/Uniswap/permit2/blob/main/src/libraries/Permit2Lib.sol#L78) which some tokens that implement `permit` do not implement like [UNI](https://github.com/Uniswap/governance/blob/master/contracts/Uni.sol). Check instead the `PERMIT_TYPEHASH` in a very...

Similar to https://github.com/Uniswap/permit2/pull/237, this is a more narrowed approach to providing a generalized test helper for SignatureTransfer. Currently, the test helpers in `PermitSignature` only generate signatures for a hard-coded `address(this)`....
