docs: Move a track to a new position within a Sonos Playlist.
          This is a convenience method for :py:meth:`reorder_sonos_playlist`.
  
          Example::
  
              device.move_in_sonos_playlist(sonos_playlist, track=0, new_pos=1)
  
          Args:
              sonos_playlist
                  (:py:class:`~.soco.data_structures.DidlPlaylistContainer`):
                  Sonos playlist object or the item_id (str) of the Sonos
                  playlist.
              track (int): **0**-based position of the track to move. The first
                  track is track 0, just like indexing into a Python list.
              new_pos (int): **0**-based location to move the track.
              update_id (int): Optional update counter for the object. If left
                  at the default of 0, it will be looked up.
  
          Returns:
              dict: See :py:meth:`reorder_sonos_playlist`
  
          Raises:
              SoCoUPnPException: See :py:meth:`reorder_sonos_playlist`
