Use transact() for Solidity functions which receive structs

[JoaoMorais96]

Fisrt of all, thank you for this library as it has helped a lot with developing in the Vechain space!

That being said, I'm trying to use the connector.transact() for a solidity function which receives a struct as input with some addresses and uints, but get the error:

eth_abi.exceptions.NoEntriesFound: No matching entries for 'tuple' in encoder registry

Would be cool to add some support to it if possible.

Thanks for your interest. Tuple structure will be supported in V2.
