Accept an additional optional Junction for incoming ERC20-XCM transfers to override the default gas limit Erc20XcmBridgeTransferGasLimit in the asset multilocation.

Looks good so far, I left a couple comments.

Another more general one: GeneralIndex seems very general-purpose for this. Maybe we should create a special AssetId to represent gas instead?

The PR is incomplete, you should also modify the XCM Weigher to apply the gas limit to the message weight and then the XCM fees.

This function is useless and increase the call stack for nothing, please remove it and move it's body inside weight_of_erc20_transfer

I think you could use if let to write this concisely instead of having a helper fn

@fgamundi next time, please notify the reviewers again via github, otherwise I won't come back until I've reviewed all the open PRs (which is not often).

Hey @librelois. Thanks for the review! I didn't request rereview because I still wanted to make more changes (partially addressing what you commented), but didn't get time before my time off
