Detect Chromecast Model / Generation in Javascript
/**
* We use this workaround to detect the Chromecast device generation.
* Unfortunately the Cast Application Framework (CAF) does not have an API for that.

* cc-1: Chromecast 1st Gen.
* cc-2: Chromecast 2nd Gen.
* cc-3: Chromecast 3rd Gen.
* cc-ultra: Chromecast Ultra
* cc-builtin: Android TV with Chromecast built-in
