document Method to browse and download files from the EJS file system

[michael-j-green]

Would be really useful if the page containing the EJS could expose a function that returns a directory structure (perhaps as a dictionary), and allow those files to be downloaded or grabbed as a byte array.

We should honestly probably just reference the emscripten filesystem docs, mentioning the object path. window.EJS_emulator.GameManager.Module.FS. No need to write an entire api to communicate to another api, seems redundant

Agreed... I think this is the best way to go.
