* New feature: RGBLIGHT_LAYERS
This feature allows users to define multiple independent layers of lighting
that can be toggled on and off individually, making it easy to use your
RGB lighting to indicate things like active keyboard layer & modifier state.
* Demonstrate built in functions for layer state checking
Also link the video in the docs.
* Follow existing pattern for setting rgblight_status flags
* Eliminate rgblight_is_static_mode since it's not needed
Just check to see if the timer is enabled directly.
On the v1.2 PCB the slave half leds go in reverse order compared to the master half.
With this change, the leds are all in order from left to right, so animations like
Knight Rider look like you'd expect.
