[StaehliJ]

Pull request

Description

The goal of this PR is to allow integrators to use MediaItem.tag this tag is no more used internally by Pillarbox. PillarboxData is now stored in the track list of the player when content is loaded.

Changes made

• PillarboxData can be retrieved with Player.currentTracks.getPillarboxDataOrNull().
• PillarboxExoPlayer doesn't override MediaItem.tag.
