Description of your pull request and other information

This PR overhauls and brings up-to-date the ORF extractor module.

TV is now handled by the on.orf.at single-page-app, replacing the former TVthek. The PR back-ports the ORFONIE recently added to yt-dlp to replace the broken ORFTVthekIE: thx @HobbyistDev, @TuxCoder, @seproDev. Resolves #32798.

Some shows (former extended live events?) may be returned as multi_video playlists: yt-dl has no support for automatic concatenation of multi_video playlists (yet), but if the same format is selected for all items (segments) it should be possible to concatenate the A-V streams without re-encoding using ffmpeg.

Livestream support (not widely tested) has been added. See also yt-dlp/yt-dlp#10052.

Similarly radio and audio clips are now handled through sound.orf.at. The ORFRadioIE extractor has been updated and made public to support this as well as residual xx.orf.at/player/... URLs. The previous per-station IEs are removed. Resolves #29394. See also yt-dlp/yt-dlp#5265, yt-dlp/yt-dlp#9581.

ORFRadioCollectionIE is added to support playlists in ORF Sound.

The PR also back-ports and re-works ORFPodcastIE from yt-dlp: thx @Esokrates.

ORFFM4StoryIE is fixed and also now gets any in-page YT media: see yt-dlp/yt-dlp#2477.

Core YoutubeDL processing is tweaked to support some not previously encountered playlist structures.

JFTR, I've tested 0153b38.

Both URLs, oe1.orf.at and sound.orf.at do work:

It seems to work, but I noticed that the I got the "second" audio stream (Audio description, (AD)), instead of the main audio stream. Not sure why.

If it helps, this is what I got after everything was downloaded:
