This library supports Azure IoT Hub over HTTP. Whilst this is great, it would be better if it:

• Used MQTT instead of HTTP to avoid polling for cloud to device messages/direct methods
• Exposed an IoT Central (the SaaS platform that sits on top of IoT Hub) interface as well as/in addition to IoT Hub to give a simplified API to access IoT Central

I've taken an unofficial IoT Central Python API that supports MicroPython that uses MQTT and exposes an IoT Central API and got it working with CircuitPython:

Would you be interested in working with me to incorporate this into this library?
