fix(de/animebase): Some fixes + refactoration

[Claudemirovsky]

Closes #2221

This PR breaks old episode links.
Also, some episodes only provide VidGuard as video hoster and I didn't create a extractor for it yet (it fucking 3:49 AM bruh)
TODOs:

1. Implement search filters
2. Somehow make the search engine work with hentai content too (is this even possible in animebase? idk)
3. sleep (optional)

Checklist:

• Updated extVersionCode value in build.gradle for individual extensions
• Referenced all related issues in the PR body (e.g. "Closes #xyz")
• Added the containsNsfw = true flag in build.gradle when appropriate (SOON)
• Have not changed source names
• Have tested the modifications by compiling and running the extension through Android Studio

Thanks for the update 🙂

Btw - Can NSFW be toggled /filtered/hidden by the user?

Have a nice sleep 😉
