grcard2-set-{adm,super}-hex commands implemented It appears that GrcardSIM2 cards allow arbitrary 64-bit keys for ADM and SUPER ADM, not necessarily consisting of ASCII digits like the specs require for standard PIN and PUK, and pySim-prog.py in fact sets the ADM key to 4444444444444444 in hex by default, which is not an ASCII digit string. If the cards allow such keys, we need to support them too.
