[Enhancement]: Add RMC protocol details to response packets automatically in handlers

What enhancement would you like to see?

In the RMC handlers, we currently take the returned RMC message and send it as-is to the client. However this has 2 main issues, both stemming from expanding the responsibility of the consumer:

1. Consumers need to write at minimum 4 lines of boilerplate for every response, to set the protocol ID, method ID, and call ID
2. Consumers need to manage the correct IDs themselves, which can lead to errors when the wrong IDs are set

If however we make it so that the consumer simply needs to return the RMC message and set all those IDs in the handlers here (since we have access to them already), we remove those issues entirely

Any other details to share? (OPTIONAL)
