Adds basic support for u/flehrad's bigswitch pcb (#3015)

* 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

* Only define Eject in keymap

+Big Switch PCB by flehrad
+=========================
+
+Designed by Don of the Board Podcast and sold as a kit by [keeb.io](https://keeb.io/collections/frontpage/products/big-switch-pcb?variant=7507922845726)
+
+### Technical Specifications
+
+ * Uses a atmega32u4 pro micro or pin compatible MCU
+ * Pins B5 and B6 connect to the pins on the Big Switch
+ * Optionally you may add a RGB strip to pin D3 for data and take power from VCC and GND
