Access Local Device Resources

[caleb-depotanalytics]

Feature Request

Two requests here (lmk if I should split them out into two separate issues):

1. The ability to execute local resource executables (appimage, exe, sh, etc...) from stlite/desktop (may not be possible).
2. The ability to just access to local fs of the device in the python code. It looks like pyodide has a mechanism for this: https://pyodide.org/en/stable/usage/file-system.html#nativefs-api
