Create EIP712 Compliant typehashes in foundry tests
Foundry utility to help test Permit signatures.
These are fiddly and a bit of a pain to get right - in no large part because it's tough to work out WHERE the signature has gone wrong.
This lib contains a simple utility for OZ delegation and, probably more usefully, EIP712 permit for an ERC20 token.
Please see the ./test file for usage instructions.
