* Add support for LED management on the Ayaneo Air Pro and possibly other models which can be found in system settings. Thanks to @Maccraft123 for reverse engineering and sharing the EC registers. Additional documentation can be found in the led_mgmt script.

* Add ability to delete a setting from system.cfg "del_setting".
