feat: allow comparing Struct types with sequence types

[antazoey]

What I did

fixes: #1451
Fixes: APE-979

How I did it

handle different types in Struct.__eq__

How to verify it

pick your poison:

    expected_dict = {"a": owner, "b": tx_hash}
    assert actual == expected_dict

    expected_tuple = (owner, tx_hash)
    assert actual == expected_tuple

    expected_list = [owner, tx_hash]
    assert actual == expected_list

    expected_struct = contract_instance.getStruct()
    assert actual == expected_struct
