feat: custom media data support and tracker control

[amtins]

Description

Add support for custom media data when provided via the mediaData property to
the player.src. Allow mediaComposition properties to be added or
overwritten when loading a new source.

// custom media data
player.src({
  src : 'urn:xyz',
  type: 'srgssr/urn',
  mediaData : {
    // custom properties
  }
})

Store the DataProvider in the player's srgOptions, allowing it to be changed
on the fly. This means it's no longer needed to extend the SrgSsr class to
redefine the default DataProvider. The only requirement is that the new
DataProvider implements the getMediaCompositionByUrn function and returns an
object of type MediaComposition.

// custom data provider
player.options({
  srgOptions : {
    dataProvider : {
      getMediaCompositionByUrn(urn) {
        // ... body of the function
      }
    }
  }
})

Add support for the trackers property to the player.options in order to
store tracker instances. This makes it easier to access trackers directly from
the player. Use of this feature remains optional.

// add custom tracker
const player = new Pillarbox('my-player', {
  trackers: {
    customTracker: new CustomTracker(player),
    anotherTracker: new AnotherTracker(player),
  }
})

Add the ability to disable trackers per playback session by introducing the
disableTrackers property provided directly to the player.src. As most trackers
take an instance of the player as a parameter. This will make it easier to access
the disableTrackers property to determine whether or not the tracker should be
disabled for the current playback session.

// disable a tracker for the playback session
player.src({
  src : 'urn:xyz',
  type: 'srgssr/urn',
  disableTrackers : ['anotherTracker']
});

// disable all trackers for the playback session
player.src({
  src : 'urn:xyz',
  type: 'srgssr/urn',
  disableTrackers : true
})

Add support for SRG SSR-compliant media playback tracking.
