[S] Change in pysim[master]: pySim.ota: Handle cases where 'secured_data' is empty

laforge has uploaded this change for review. ( https://gerrit.osmocom.org/c/pysim/+/37483?usp=email ) Change subject: pySim.ota: Handle cases where 'secured_data' is empty ...................................................................... pySim.ota: Handle cases where 'secured_data' is empty while it's true that in situations where response_status == 'por_ok' we are guaranteed to have a 'secured_data' key in the dict, its value could well be b'', which in turn causes us to run into an exception, calling a decoder on an empty byte value; let's avoid that.
