This commit adds basic support for a TH02 based Grove Sensor which is
silkscreened as
Temperature&Humidity Sensor (High-Accuracy & Mini ) v1.0
https://www.seeedstudio.com/Grove-Temperature-Humidity-Sensor-High-Accuracy-Min-p-1921.html
This is a modified variant of a SHT2* driver, and still needs some
changes to be more useable. It is written to assume you want to use the
High Precisions (slow sample rate)
