Jason Striegel 88aeec9f69 Fix setWindow bug, add CS pin for Clue compatibility. (#180)
* Fix setWindow bug, add CS pin for Clue compatibility.

- corrected bit shift in setWindow that broke high addresses
- added csPin to constructor (will now work with adafruit clue)
- small adjustments and comments to init routine based on working arduino driver

* Update main.go

Updated test example with CS pin.

* Reverting unnecessary (no-effect) change in setRotation.
