Describe the bug

cast send used in format seth call [<options>] <to> <sig> [<args>...] does not correctly parse function signatures if they contain tuples. It seems this problem stems from the ethers-rs repo, specifically here.

It looks like line 261 in particular would be causing the issue since is splits the calldata arguments with '(' as the delimiter in order to separate input and output args, but that would break if there are any tuples present as args.

This issue is also present in seth, although the error message is a little clearer here as it outputs seth-abi: error: unexpected character "(" at position 0 in "(bytes1,bytes32,uint64)".

@mattsse Assigning you to this since it's the same underlying issue as #2025 and you assigned yourself to that one
