youtube thumbnails using storyboards with `network=true`

[vlnka]

YouTube offers small thumbnails (images changing every few seconds, inside a mhtml file) for every video - yt-dlp format id sb0 (180p), sb1 (90p), sb2 (45p), sb3 (27p).

Would it be possible implement those for youtube videos? It would be much more effective than the default network method

Example of what the mhtml file looks like when opened:

Thank you

If your going to add support for yt-dlp then there also other sites that also have thumbnails like archive.org.
