Make the extension available as web extension (vscode.dev)

Web Extensions

VSCode launched https://vscode.dev/ that is using so called "web extensions".

Thus make the TinyPNG extension available as such.

Thoughts:

According to the web extension author guide,

Importing or requiring other modules is not supported. importScripts is not available as well. As a consequence, the code must be packaged to a single file.

Thus this would mean we would need to bundle the extension together with the tinify package.
