Co-authored-by: kwerdenker <sebastian.spindler@gmail.com>

* Manually apply white channel to array

* Move where convert_rgb_to_rgbw is called

* Fix type for rgbw led struct

* Add changes to Ergodox EZ

can revert if deemed necessary

* Revert "Add changes to Ergodox EZ"

This reverts commit aa44db198d40d758ca10470eb94615513592d1dd.
