Add support for tuples in function parmeters

[Mouradif]

Currently the Huff parser throws an error for functions defined like this:

#define function callFunction(address, (address, uint256), bytes) nonpayable returns ()

The error:

Error: Invalid Argument Type: "(" 

The original function signature in Solidity is:

function callFunction(address, DyDxAccount.Info memory, bytes memory);

Where DyDxAccount.Info is:

library DyDxAccount {
    struct Info {
        address owner;
        uint256 number;
    }
}

The function's signature is 0x8b418713 or keccak256("callFunction(address,(address,uint256),bytes)")

My current workaround is to simply define the function signature as a constant for my function dispatch but it would be great to have support for tuples or even structs one day
