Subject: [PATCH] Add support for Tikteck Bluetooth bulbs (#4843)

* Add support for Tikteck Bluetooth bulbs

Adds support for the Tikteck RGBW BLE bulbs. These don't provide "true" RGBW
support - at a certain point in RGB space, the white LEDs turn on. Each bulb
has a specific key that needs to be extracted from the Android app.

* Update tikteck.py
