R167 massdrop ctrl

The main layer is a ~standard QWERTY layout with the ALT/GUI swap for macOS in addition to shifting the Fn key one to the right so cmd/alt line up nicely. Addionally, I rarely use PgUp/Dn, so I've remapped those to volume control.

The most interesting bit is the shortcut Fn + Esc which triggers the macOS sleep shortcut (CMD + ALT + Eject) and then disables LEDs since the computer will wake up peripherals even while the display is asleep. Keyboard is returned to all LEDs on after pressing any key.
