thank you for your suggestion to use an external program and to provide
the source for it. At a pinch, I would have used `xxd -r -ps tmp.txt'
with \write18 for converting Hex back to Bin. In fact, I used xxd to
produce the hexdump from the original file. (Xxd is a helper program
that ships with the Vim editor.)

Of course, I hoped to elegantly get along without the need to resort to
an external program, but this does not seem to be possible.

Thank you anyway!
Best regards,
