Yoshio HANAWA c2689effd9 Initial support for SHT2x Temperature/Humidity sensor driver

npotts bdca7a67c9 Adde unit tests for TH02 & Minor improvement 
- Added ability to change sample resolution
- Added unit tests for TH02Driver.  The way the functions are written,
it will be hard to get a fully working .Sample() coverage with my
limited understanding of gobot's testing API.  The chip is rather needy,
and each sample requires multiple read and write steps, so getting both
read and write for 2 independant measurements it a little over my head
without some more code viewing.

Id rather get this checked in and think of a better way to do this.
Otherwise, this does test the functionality

npotts b1825f2e90 Added rudiementary support for TH02 Grove Sensor 
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)

Graeme Cross 95b0fe880f Improved BME280 humidity initialisation so that it does not override existing

The humidity oversampling rate is set to 1 (as per Section 3.5 of the BME280
data sheet).
