[Feature] Xg Mobile Lighting API

- add ability to toggle xg mobile lighting (and finally disable it without Crate).
- no ui buttons provided, I'm too tired for this. You can add them into Xg mobile section.
- It's impossible to get current status of light (I think this is common issue for Aura API). Even Crate can only set status.

How I managed to find this API: firstly I checked other properties of ASUS WMI, but didn't find anything. Then I decided to check specific AURA devices and found two - both related to Xg Mobile. Then I used Wireshark to trace outcoming data to these USB devices, some pattern-matching and finally I got the params to send
