feat: Add MQTT command support and CC1101 commands
This commit introduces new functionality to process Signalduino commands received via MQTT, significantly enhancing the integration capabilities of PySignalduino. Key changes include: - Extended the command list in `signalduino/commands.py` to include new MQTT-related commands and specific CC1101 register commands. - Implemented and integrated the MQTT publisher logic within `signalduino/controller.py`. - Introduced and adapted unit tests in `tests/test_mqtt_commands.py` and other test files to ensure full coverage of the new MQTT command processing.
