Adding Ambient light-controlled keyboard backlight using WinRT library

Is your feature request related to a problem? Please describe

No, it isn't, but it would be nice to add this feature since some Asus laptops （mostly Zenbooks）have this feature with the AsusOptimization service enabled.

Describe the solution you'd like

Adding feature for reading and controlling the keyboard backlight based on ambient light sensor readings.

Describe alternatives you've considered

Keep AsusOptimization running with g-helper, with the background process AsusOSD.exe killed to avoid confilcting with g-helper's OSD, but AsusOptimization conflicts with g-helper on the fan settings and keyboard backlight levels.

Device and Model

Asus Zenbook UX5406

Additional information.

I wrote a very simple demo here to show how you can read ambient light sensor values.
