Minimal implementation for reading/writing files in the root
directory of a FAT16/FAT32 file system.
Can read/write from raw disk devices, and no longer relies on
operating system support for mounting the file system.
Currently assumes Imager will always be run on 'little endian'
architectures such as Intel and ARM (at least under Linux).
If there is a use-case for big-endian (anybody still using Sparc?)
this may be revisited later.
- If a drive is formatted APFS it will have a seperate disk
devices for physical drive (e.g. /dev/disk2) and volumes
(e.g. /dev/disk3).
Need to unmount all, or opening the device for
writing will subsequently fail.
(User will see an "Error running authopen" error in Imager
in that case).
- Also do not show APFS volumes seperately in the disk
selection dialog. List mount points under physical drive
instead.
Closes#501
Only supported when NetworkManager is used on the Linux distro
as wpa_supplicant itself does not support reading PSKs through
DBus, only setting them.
Closes#457
