Profpatsch 6376458424 sane: Add support for the unfree Fujitsu ScanSnap drivers
This adds the scanner files already linked from the
`etc/sane.d/epjitsu.conf` file, which are extracted from the Windows
drivers and mirrored on GitHub.

Being a Japanese hardware vendor, Fujitsu’s software release &
licensing methods are horrifying, but their scanners are some of the
best, so we should definitly have discoverable support for them, which
this patch hopefully adds.

Inspiration was taken from the following sources:
