* [Keymap] Add vitoni layout for GMMK Pro (ISO) Keymap has layered cursor keys similar to laptop keyboards. * Configure RGB defaults for startup * Configure encoder to change value/brightness on FN layer * Remove FN layer and add dedicated RGB layer * Make RGB layer sticky (using TG) to avoid holding FN while configuring RGB * Add RGB indicators for active layers * Add RGB indicator for active RESET mode Signed-off-by: Victor Toni <victor.toni@gmail.com> * Configure idle / USB suspend settings * Add RGB fade in when resuming after suspend * Add RGB fade out before suspend * Add fade out before idle * Add breathe effect when idle
