Backlight Breathing for Planck and Atomic

* Updated personal layouts

* tweaked personal

* Nightly - Audio Cleanup

Refactored the LUTs. Abstracted some of the registers out of audio to
use more functional names. Split audio into audio and audio_pwm. WIP

* nightly - collapsed code

* Added check for note playing to LEDs

* Usability tweaks

* TWEAE

* nightly

added extra kcs to keymap common

* turned on Plank audio

* Added backlight breathing to atomic

* reverted accidental merge

* adds backlight pulse to planck
