pysim-prog: also allow raw hex adm pins besides numeric ascii
At the momemnt pysim takes the supplied ADM pin number and interprets
it as ascii string. This ascii string (max 8 digitis) is then padded
with 0xff bytes if necessary and sent to the card.
This limits the range of possible ADM keys and it is not possible
to deal with situataions where the ADM pin consists of arbitrary
bytes. At the momemnt pysim-prog forbis anything that is longer
than 8 digits. Lets also check if there are 16 digits and if yes
interpret them as raw bytes.
- when the adm pin is 16 digits long, interpret the string as raw
bytes (hex).
