Tells if trick mode tracks are currently enabled if available.
Trick mode tracks are video tracks with a generally lower frame rate, allowing for example to play content fast-forward in an efficient way.
Note that isTrickModeEnabled returning true does not always mean that
a video trick mode track is currently displayed, as it depends on whether it is
actually available on the current content.
You can know if a trick mode video track is currently playing by checking if the
track returned by the getVideoTrack method has its
isTrickModeTrack property set to true.
