* Adds basic support for u/flehrad's bigswitch pcb
- also adds support for OSX Eject/Power
The function of this key depends on the version of OSX and if you
have physical media. For a macbook pro 2017 holding this key down
brings up the shutdown dialog. If you wrap it in LCTL and LSFT the
screenlock turns on immediately.
* Switch to Layout Macro
- add a code for OSX Sleep
* Add a README
* Turn on RGB by default
* Add info.json
* Address comments by @drashna
