PS1:
I have tried this out. and fed it some APDUs (the testcases from current
master, /tests/pySim-shell_test/apdu/test_apdu.script). Case 1-3 seem to work
fine but when I enter 00a40004023f0000 (case 4) it seems to have problems.
Leaving out the Le field also does not help.
Here is what I tried:
./pySim-trace.py stdin-hex
INFO root: Opening source stdin-hex...

I also wonder what is with the responses? Those aren't intended to be
analyzed?. Maybe I am just using it wrong. As I said, some more info in the
commit message would be helpful.

I think it would be good to write a sentence or two what this is patch is about
and how it can be useful. I can see it is for pySim-trace, but I do not get the
usecase.
