[Reddit] Allow downloading from quarantined subreddits

[Unit193]

Howdy,

Seems yt-dlp in commit f0e5366 added the ability to download from quarantined subreddits, this could be useful in gallery-dl too.

This worked for a test, but isn't technically correct.

I tried this with the link from the yt-dlp issue and I'm only getting 403 error ({"message": "Forbidden", "error": 403}). I've also used the unquoted version {"pref_quarantine_optin": true} as cookie value, changed the domain for API requests from oauth.reddit.com to www.reddit.com, used public/private access tokens and no difference.

Checking that, seems the community was banned, so it no longer exists. I went down this list looking for something moderately innocuous and seems r/ApolloMoonLandingHoax still works with the example changes above. It's interesting to note though, while that pulls up fine, /r/DrawPeople (no idea what's on here, view at your own risk) requires one to log in, so gallery-dl gives [reddit][error] AuthorizationError: Insufficient privileges to access the specified resourc whereas the former subreddit worked fine.

Example output blow.

So the problem was me testing with an already deleted subreddit ...

I added the cookie for public access tokens in https://github.com/mikf/gallery-dl/commit/2d34d8ff8bbec102358ef89ef5732fcb7afa0d25. According to my tests, it has no effect when using a private token. In that case you need to visit the quarantined subreddit with your account and agree to "view this community" there.

Sweet, thanks!
