The import adafruit_azuireiot statement throws an error from the 6.x adafruit library bundle. `from adafruit_azureiot import IoTHubDevice` It looks like MiniMQTT is already aware of this issue but this issue was never opened on this repository. [MiniMQTT Issue 51](https://github.com/adafruit/Adafruit_CircuitPython_MiniMQTT/issues/51) [Link to referenced comment](https://github.com/adafruit/Adafruit_CircuitPython_MiniMQTT/issues/51#issuecomment-729772968) I believe this is the import that is affected in the iot_mqtt.py. [iot_mqtt.py](https://github.com/adafruit/Adafruit_CircuitPython_AzureIoT/blob/2a83561e0585e201fae2316c7d5d4f1806512ac0/adafruit_azureiot/iot_mqtt.py#L35) Please let me know if you need further information.
