Pull request overview

This PR fixes the type annotations for the send() method in the Q7 B01 device trait to accurately reflect the types accepted by the underlying send_decoded_command function.

• Updates send() method signature to use CommandType and ParamsType instead of more restrictive types
• Adds necessary imports for CommandType and ParamsType from b01_channel
