There was a problem hiding this comment.
nit: add new generated file type locations into .gitattributes file, we should probably do this with the json attribute files as well?

Summary
implement withdrawals of ERC20 tokens that are of type
AstriaBridgeableERC20(see implemented contract).Background
we want to be able to withdraw ERC20 tokens that are bridged to a rollup.
Changes
AstriaBridgeableERC20which is a standardERC20contract with additional functionality for minting (not used by the withdrawer, implemented/tested here implementAstriaMintableERC20, update deposit tx to support ERC20 mints astria-geth#20) as well as functionality for withdrawingIAstriaWithdrawerwhich is implemented by bothAstriaWithdrawerandAstriaMintableERC20.IAstriaWithdrawer. both native assets and ERC20 withdrawals have the same event signatures, so no additional code was needed for the withdrawer itself.AstriaBridgeableERC20, theASTRIA_BRIDGE_WITHDRAWER_ETHEREUM_CONTRACT_ADDRESSis set to someAstriaMintableERC20, andASTRIA_BRIDGE_WITHDRAWER_ROLLUP_ASSET_DENOMINATIONis set to the rollup asset's denomination as represented on the sequencer. for example, if the asset is represented on the sequencer istransfer/channel-1/usdc, that is the rollup asset denomination. thename/symbolof the ERC20 contract are not relevant.Testing
unit tests
