Before this PR, Invidious assumed that every playlist had at least one video.
When a playlist had no videos, Invidious was throwing an "Index out of bounds"
exception.
The following API endpoints were impacted:
* api/v1/playlists/:plid
* api/v1/auth/playlists/:plid
Fixes issue 4679
When visiting /api/v1/popular and popular endpoint is disabled
Before:
500 {"error":"Closed stream"}
After
403 {"error":"Administrator has disabled this endpoint."}
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.
Invidious assumes that every playlist will have at least one video
because it needs to check for the `index` key. So if there is no videos
on a playlist, there is no `index` key and Invidious throws
`Index out of bounds`
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
Before this PR, Invidious assumed that fetching the DASH manifest from
YouTube will always be successful and didn't check the status code.
That meant that if YouTube gave a rate-limiting page, invidious would
return an HTTP 200 response with the 'application/dash+xml' Content-Type
header and the YouTube ratelimiting page as the body.

This PR parses the start and end time for clips.
It also adds a new, dedicated API endpoint (`/api/v1/clips/{id}`) for
retrieving the start and end time of a clip.
Here is a sample response from that new endpoint (`video` is a video object,
as described in https://docs.invidious.io/api/common_types/#videoobject):
GET `/api/v1/clips/UgkxxPM3BRphCAPLP88YoUGuj79KXPfpNNO_?pretty=1`
Response:
```
{
"startTime": 8842.645,
"endTime": 8855.856,
"clipTitle": "✂️ Kirby is pink!",
"video": {}
}
```
Closes issue 3921
* Add stats-based /videoplayback blockage status
* Count when YouTube returns wrong video as failure
* Cast playback stats hash type prior to return
* Bump stats refresh timer to 10 minutes
