Interesting, because a lookup table would be only 15 lines by my
calculations for 2x mode.  1 byte returned for each nibble 0-F.  6x is
another story, 3 bytes per nibble, but maybe that could be simplified.
Maybe using the 2x table in a clever way could get you what you need for the
6x mode.  It is a neat problem.
