Merge branch 'modular-data-extract'

Commits in this branch are prefixed with "Extraction:"
This branch refactors data extraction. All such functionality has been moved to the yt_data_extract module.
Responses from requests are given to the module and it parses them into a consistent, more useful format.
The dependency on youtube-dl has also been dropped and this functionality has been built from scratch for these reasons:
(1) I've noticed youtube-dl breaks more often than invidious (which uses watch page extraction built from scratch) in response to changes from Youtube, so I'm hoping what I wrote will also be less brittle.
(2) Such breakage is inconvenient because I have to manually merge the fixes since I had to make changes to youtube-dl to make it do things such as extracting related videos.
(3) I have no control over error handling and request pooling with youtube-dl, since it does all the requests (these would require intrusive changes I don't want to maintain).
(4) I will now be able to finally display the number of comments and whether comments are disabled without making additional requests.

-    PostProcessor objects can be added to downloaders with their

-    successful download, it will take its internal chain of PostProcessors
-    and start calling the run() method on each one of them, first with
-    an initial argument and then with the returned value of the previous
-    PostProcessor.
-
-    The chain will be stopped if one of them ever returns None or the end
-    of the chain is reached.

-    PostProcessor objects follow a "mutual registration" process similar
