Use message structures defined in pythnet sdk (#377)

* Use message structures defined in pythnet sdk

Since the custom serialization implementations are solana specific and
mainly for reducing the binary size, they are kept in this package via
a custom trait.
Deserialization functions were removed since they were not used and
the default serde provided by pythnet sdk should work identically.
Serialization tests are now repurposed to test our custom serialization
and the general deserialization lead to the same original structure.

* Set resolver version to 2 to avoid some feature unifications

The old resolver adds the quickcheck feature on the pythnet-sdk
dependency for non-dev builds as well which leads to compile errors.
