optimistic-wrapped-withdraws

Wrap a L2 ERC20 withdrawal event as an ERC1155 subtoken on L1

Disclaimer

This is incomplete and unsafe. Do not use this in production.

This was written when Optimism's bridge spec was much simpler, a safe and production ready version of optimistic-wrapped-withdraws could be developed with the new Optimism bridges... but we have no plans to do this at the moment.
