Needs support for Android 11 file permissions

[wfowler1]

Currently the app uses its own file explorer to select a ROM to play, but Android 11 changed the filesystems permissions system. Now it's impossible to load a ROM from the SD card, you can only use the device's internal storage. Other emulators have adjusted for this, like Dolphin, so it shouldn't be too hard to do
