emg: Added emg sensor C source

Added the C source for the emg sensor with necessary changes to cmake,
examples, docs.

    * Renamed all files with groveemg to emg
    * Replaced all instances of groveemg with emg
    * Added C source for emg sensor
    * Updated all cmake files
    * Added C example for emg sensor
