Support using icons externally

Information:

Previously projects would use the atom icons repository because it was an actively maintained collection of file type icons that could be easily used on websites, but it's become unmaintained.

This has a better collection of icons and is being maintained for VSCode, but it's a typescript extension that's not as easy to use.

If there was some way to use the icons in an easy way, even just a single JSON or CSS file with the file extension mapped to the icon file name would make the efforts even more broadly usable.

For now, you can clone and build the project and get a vsicons-icon-theme.json file in the dist > src folder.

I saw that, but it doesn't appear to have all the file extensions like language.ts does, for example the rust entry is missing the rs file extension in the json file.

That's mainly because there are some icons that are not tied to a particular file extension but to a language id. That allows dedicated extensions to contribute with the proper file extensions, so we don't have to maintain and curate the list of extensions ourselves.

In the case of Rust, the language id is rust. You can see that the rust analyzer extension supports that language id and then defines the associated extensions: https://github.com/rust-lang/rust-analyzer/blob/master/editors/code/package.json#L1735

The extensions in language.ts are not used at all. They're there mostly as a description field, but they're not a complete list of extensions.
