Save/Open menu options

We should add the ability to save/load the current DOM scene to a project directory.

This would be a precursor to something like "publish top Github", "publish to Glitch", or "upload to device", as well as actually sharing the scene code files.

sharing to glitch would only be usable on studio/exokit though right? regular browsers would not use the reality layers/iframes

would this include publishing the studio index.html, three.js, example htmls, etc?

My thinking is there are two distinct modes here:

• Each layer can be exported separately and this would not require anything on the reader side
• The whole scene, with all layers, can be saved/exported

This is very similar to how Adobe Photoshop works when you do a save/export.

Downloaded a basic site with a few lines of code, something more complex like a-painter does not work right away though, it has the main files but is missing some asset obj mtl png files.

Going to open a PR with this functionality, as it will feed into #42.

For saving full site contents, the main approach is to use service workers: exokitxr/exokit#879

And the main prerequisite of that is https://github.com/modulesio/window-sw, which has a prerequisite of implementing the xhr and fetch interceptions such that they can be routed to the service worker.
