[XS] Change in pysim[master]: pySim-shell: allow checking of APDU responses

dexter has uploaded this change for review. ( https://gerrit.osmocom.org/c/pysim/+/38606?usp=email ) Change subject: pySim-shell: allow checking of APDU responses ...................................................................... pySim-shell: allow checking of APDU responses The "apdu" command allows us to send custom APDUs to a card. This command is often used in low level initialization scripts or tests. To stop the script execution in case of an error, the command allows us to specify a status word that must match the status word of the response. But we have no such mechanism for the response itsself. Let's add another parameter where we can pass a regex that the response must match.
