chore: Restructure the channel modules
This provides a separation between the lower level protocol specific channels (MQTT vs Local) and the Application/RPC level command handling channel modules. This updates the pydoc to clarify the responsibilities between each layer. The motivation is from noticing that b01 introduced a number of new channels, protocols, traits, and it seemed worth separating for clarity as we want to add new developers to the code base.
