Support root directory browsing

[Denis11212]

Previously, I used the application https://github.com/Raival-e/Prism-File-Explorer; it is also open source and can access the root folder of the device without root rights. It may be possible to examine its source code and understand how the same functionality can be done in Material Files. I like Material Files, but I have to keep Prism File Explorer on my smartphone to access some system folders.

That's an interesting app, since I also occasionally want to browse the root folder without root permissions. Mind if I ask, why did you change from Prism to Material Files, then?

@e-t-l Because this app has support SMB protocol to view data on a network drive
