* 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
