The transcript logic in Invidious was written specifically
as a workaround for captions, and not transcripts as a feature.
This commit genericises the logic a bit as so it can be used for
implementing transcripts within Invidious' API and UI as well.
The most notable change is the added parsing of section headings
when it was previously skipped over in favor of regular lines.
The new comment format is similar to the description's commandRuns.
This should fix the issues with most comments but there are still
some more changes that would need to be made like adding support for
formatting (bold, italic, underline) and channel emojis.
Fixes issue 4566
Returns the 'isPostLiveDvr' field in the videos API when the video
is a post-live DVR (= ended livestream that hasn't been reprocessed
into VOD yet).
Example taken 10 minutes after that livestream ended:
/api/v1/videos/euqnWk-uP6M
{
...
"isPostLiveDvr": true,
...
}

PR #4037 introduced a workaround around YouTube's new integrity checks
on streaming URLs. However, the usage of this workaround prevents
storyboard data from being returned by InnerTube.
This commit fixes that by only using the workaround when calling try_fetch_streaming_data
The Caption object does not actually store any text lines for the
subtitles. Instead it stores the metadata needed to display and fetch
the actual captions from the YT timedtext API.
Therefore it may be wiser to rename the struct to be more reflective of
its current usage as well as the future usage once the current caption
retrival system is replaced via InnerTube's transcript API
