Ok, I like this output esp, because you can reverse it with
"xxd -r -p". Maybe we should also request an md5sum just to
be sure we have the same binary.

so the requested commands would be something like:

# xxd -p /path/to/sfdp
# md5sum /path/to/sfdp
# cat /path/to/jedec_id
# cat /path/to/partname
# cat /path/to/manufacturer
