Returns true if trickmode playback is active (it is usually enabled through
the setPlaybackRate method), which means that the RxPlayer selects "trickmode"
video tracks in priority.
Returns false in other cases.
Note that this doesn't mean that the player is currently playing a trickmode track nor that it is even playing a content, only that it selects trickmode tracks in priority.
To switch on or off this mode, you can use the setPlaybackRate method.
