[feature-request] - option to generate NFO and other metadata about the downloaded file

[IlmariKu]

I'm using Jellyfin to organize my media and when I'm using Yle-dl to watch the content, Jellyfin is not recognizing the video files or doesn't know anything other about them, than the filename. Areena does contain descriptions and lot of other info that would be needed to fill the .nfo-file.

NFO-files are just xml in a specific format, saved next to the file.

Can or could yle-dl be adapted to save the description, name of the film and other metadata present in the movie page? I see there is an option for the metadata-json, so some info is already gathered there.
