Notes:
* The functions `extractor.common._extract_..._formats` are still kept for compatibility
* Only some extractors have currently been moved to using `_extract_..._formats_and_subtitles`
* Direct subtitle manifests (without a master) are not supported and are wrongly identified as containing video formats
* AES support is untested
* The fragmented TTML subtitles extracted from DASH/ISM are valid, but are unsupported by `ffmpeg` and most video players
* Their XML fragments can be dumped using `ffmpeg -i in.mp4 -f data -map 0 -c copy out.ttml`.
Once the unnecessary headers are stripped out of this, it becomes a valid self-contained ttml file
* The ttml subs downloaded from DASH manifests can also be directly opened with <https://github.com/SubtitleEdit>
* Fragmented WebVTT files extracted from DASH/ISM are also unsupported by most tools
* Unlike the ttml files, the XML fragments of these cannot be dumped using `ffmpeg`
* The webtt subs extracted from DASH can be parsed by <https://github.com/gpac/gpac>
* But validity of the those extracted from ISM are untested
