Adafruit-circuitpython-typing

Add Protocols for representing LED-like classes for use as types in type annotations.

To use in CPython, `pip3 install adafruit-circuitpython-typing`.

Read the [docs](http://circuitpython.readthedocs.io/projects/circuitpython-typing/en/latest/) for info on how to use it.

Added `I2CDeviceDriver` duck typing class for describing classes using `I2CDevice`.

To use in CPython, `pip3 install adafruit-circuitpython-typing`.
