led-control: powermode debug
led-control: compensate for uneven color channel scale from userspace
led-control: make white (255/255/255) more realistic
led-control: more changes, and add system notif brightness control

since AOSP ROMs don't use the low power mode, repurpose it to control system notification brightness.
detection is based on the specific color the ROM (RootBox) called for during normal charging events. ymmv.
led-control: recognize more system notifications
led-control: added addends for RGB LEDs / custom white balance controls
led-control: bugfix

bugfix to allow wb-adjustments to apply to neutral colors and not just pure white.
