Support MPEG-DASH native in-manifest thumbnails #1705
Description
Related Problem:
Arguably, the best way to supply thumbnails of a video today is through the use of specifying the thumbnails prop of the player to link to some .vtt file.
It has recently come to my attention that .mpd (MPEG-DASH) manifests have native support of these thumbnails within them, without the need to store another source of truth about thumbnails somewhere else.

Describe:
I'd love for thumbnails to be inferred from the .mpd manifest if no other explicit source is given.
Alternatives:
I've considered parsing the manifest myself and somehow translating that into the object structure Vidstack expects. Although I think that might work, it feels error-prone and expensive to introduce manifest parsing into a project just for this.
