Description

Protect calls to permit against front-running by catching failures and not reverting the transaction if the signature was consumed but nothing else nefarious happened.

Unfortunately this adds a fair bit of bytecode, and makes CompositeLiquidityRouter go over the limit (at least with its current non-viaIR compilation).
