        public void updateMediaPlaylistTags​(java.util.Collection<? extends TagModel> tagsToUpdate)
        Update a list of "Media Playlist Tags" (as defined by the Apple spec) in the MediaPlaylist. It is assumed that both the list of tags provided and the list of tags in the current MediaPlaylist contain no repeated tags (i.e. no more than one of any one TagModel type), as should be the case for Media Playlist tags. Media Segment tags should not be included since those are stored in the segment entries themselves.
