pause method
Pause a currently-playing track.
A paused track is not considered "stopped," so its MIX_TrackStoppedCallback will not fire if paused, but it won't change state by default, generate audio, or generally make progress, until it is resumed.
It is legal to pause a track that's in any state (playing, already paused,
or stopped). Unless the track is currently playing, pausing does nothing,
and returns true. A false return is only used to signal errors here (such
as MIX_Init not being called or track
being NULL).
\param track the track to pause. \returns true if the track has paused, false on error; call SDL_GetError() for details.
\threadsafety It is safe to call this function from any thread.
\since This function is available since SDL_mixer 3.0.0.
