Revert "pySim-prog: ADM code can be longer 8 digits, it's implementation specific."

This reverts commit a51592e1807c1d13f88b32275aa4a8a77d7d3b40, which
broke the use of ADM pins on sysmoUSIM-SJS1 (and possibly others?)

The ADM pins have so far always been specified as ASCII decimal digits,
i.e. something like "-a 53204025" gets translated to hex "3533323034303235"

After the above patch this is broken and gets instead translated to
"53204025ffffffff" in hex which obviously breaks.  Let's revert back to
the old behavior to make it work again.
