Summary

🚚📝✂️

This pull request refactors the codebase to split the extractors into different files based on their domains or categories. It moves the VLiveWebArchiveIE extractor class from _extractors.py to archiveorg.py and updates the comment of the process_subtitles method in naver.py accordingly. This improves the organization and readability of the code.

Oh, we're the brave extractors of the web
We fetch the videos from every site and thread
But when the code gets messy and too long
We move the classes to where they belong

Walkthrough
