Web File System Access API

Hi, first of all I wanted to thank you for your hard work on emscripten. Recently I have been working with WORKERFS filesystem which I find vital in my project. Kudos to whoever came up with this idea and implemented...

Moving forward into 2021, there is now [File System Access API](https://developer.mozilla.org/en-US/docs/Web/API/File_System_Access_API) available in web browsers, so I wanted to check if there has been any research or implementation or at least a plan to do so?

If not considered in foreseeable future, what would be the best material to look into for implementing this custom FS?
