changed dht library to adafruit-circuitpython-dht

PR to get Francesco's DHT library update...

[gmos]

Thanks Francesco, I'll give it a test. Glancing over it I saw one thing to change. self._sensor = sensor(pin) should be self._sensor = sensor(pin[0]) since the pins in AE are class AE_Pin members which are tuples with the actual BCM pin number at position 0.
As you don't have a DHT (right?) to test seems best I'll make it working here and add it to the baseline. ### you OK with that?

No problem, take it.

I want to discuss this in our next meeting. The proposed DHT11 library is for Circuit Python. It requires a glue layer too, see https://learn.adafruit.com/circuitpython-on-raspberrypi-linux/installing-circuitpython-on-raspberry-pi
Since Adafruit has announced to stop support for all their Python libraries, except the "circuitpython" series, we may bump into this more often in future. So that would mean we will need to investigate the use of the glue layer.
Let's discuss next time (@MichielBbal )
