Synchronous `fs` in browser

This demo executes tests of synchronous Node.js API built on top of File System Access API in browser.

There are two tests:

OPFS — virtual file system built into browsers.
Native File System Access API folder — a real folder that user explicitly grants permission to.

See the assertions run in the browser console.
