Allow extensions to return qualityMap for mp4 URLs

[cweiske]

Describe your suggested feature

The Miru video player shows the current video resolution in the lower left ("1920x1080"). When clicking on it, it only shows "No quality available" for mp4 videos - only HLS allow quality selection.

It would be nice if extensions could return multiple URLs from the watch() method, together with video quality/resolution labels.

Example: The media.ccc.de API provides URLs for different resolutions and formats.
