feat: refactor for zksync abstraction

[DanielSchiavini]

What I did

This PR includes a few small changes to make zksync integration possible:

• Fix prepare_calldata for constructors
• Add Env.create_deployer method so it may be overridden
• Fix sign_typed_data in Google Colab (the address was getting lost)
• Change sign_typed_data to receive the full message instead of its components (the schema actually requires primaryType.
• Improve RPC error messages
