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.
