Amazfit GTS 3: Initial support (#2871)

Add basic initial support for the Amazfit GTS 3 based on Xiaomi Smart Band 7 support.

What was already tested (other features might work too):

**Implemented features**
    Connection
    Reconnect after Airplane mode
    Set time
    Notifications
        Send to band
        Delete notifications on phone/band when deleted on the other
        Calls
        Custom notification icons
        Handle + ack notification replies from band
    Music (with youtube music)
        Music Info
        Volume
        Music buttons
    Find Phone from band / stop on band when stopped on phone
    Battery Info (request, parse)
    Flash Watchface
    Night mode (mode, schedule)
    Lift wrist (mode, schedule, sensitivity)

(Not) working features might be similar to Miband 7.

Tested on
FW: 7.42.5.1
HW: 0.76.17.4
