User Messaging.
This class provides one command and one event which can be used by a NCP host and target to implement a communication mechanism with a custom proprietary protocol. An application must decide whether and how the command and event are used. The stack does not produce or consume any messages belonging to this class.

Used by an NCP host to send a message to the target application on device. The application on target is must send the response with sl_bt_send_rsp_user_message_to_target.
