Add support for Nanoleaf Aurora Light Panels (#13456)

* Added support for Nanoleaf Aurora Light Panels

* aurora light module - fixed lint errors

* aurora light module - use SUPPORT_COLOR instead of SUPPORT_RGB_COLOR

* nanoleaf aurora light - support_hs_color instead of rgb

* review comments from armills implemented

* nanoleaf aurora lights - put attributes into constructor (pylint)
