Add ZIP 解压增强版 extension

[THE-END-MC]

(Chinese)这个扩展可以通过zip文件的URL/Data:URL来获取ZIP里面的内容，并且把内容提取为文本或者Data:URL
这个版本是另一个自制未发布扩展的增强版，添加了获取ZIP里面的内容的Data:URL和获取ZIP内的文件列表

There's already a ZIP extension for turbowarp on the gallery, I doubt this will be merged.

even though this pull request probably won't get merged (because there's already an existing Zip extension that has more functionality) i'll try to review this anyways for any future pull requests you might make:

some final notes: you should make a branch for each separate pull request you're gonna make, instead of using the master branch. if you don't already know how to use git or github, you could try learning it somehow (here's a github documentation page that contains the basic flow).
i'm actually not sure what to do if you've already commited to master, maybe delete the repo (after making a backup) and start over or something. or perform some git trickery to reset the commit history to a clean state.

overall: please test your contributions as a whole! as in, clone/download your fork and run it locally. make sure your local copy of the website works, that your extension is in there and the extension itself works.

(also reminder if you didn't see the comment above:)

and of course, read CONTRIBUTING.md
