Eip712Signer

An adapter contract to plug in front of the Safe SignMessageLib, producing EIP-712 signatures for Snapshot votes

Todo

The integrity checks implemented in the Roles Modifier contract require all branches of logical expressions to have identical type trees. Due to this limitation any role can only scope EIP-712 messages of a single structure.

A potential workaround for this could be adding a fallback() function to the Eip712Signer contract so we can use a dedicated selector for signing each message type.
