pySim-prog: Add option for hex ADM keys

pySim-prog would implicitly try to use the raw or hex-escaped format
depending on the length of the parameter, now there is the option "-A"
to explicitly specify the hex-escaped ADM1 key.

pysim-test.sh: Explicitly use the "-A" option to pass the hex adm1 key
for wavemobile cards
