Update scanner firmware (USB)

Update the scanner's firmware via USB.
Older versions (between {10/20}.0.0 and {10/20}.1.2) will need to enable the scanner's WiFi, send the update this way, and disable WiFi again.
Versions starting with {10/20}.2.0 support a fully functional update via USB, and do not require WiFi anymore.
The method used is decided by the scanner automatically.
