more robust resolution handling
Currently, we have a hard-coded list of resolutions. Since Invidious reports the actual resolution of a stream and does not hard-code them to a fixed value anymore, resolutions that are not in the list won’t be handled, and the stream cannot be played back.

Instead of hard-coding even more resolutions (and inadvertently might not cover all), we revert the list back to a finite set of resolutions, the users can select from. All other resolutions are handled dynamically and compared to the existing set of defined resolutions when selecting the best stream for playback.
