[M] Change in pysim[master]: transport: do not catch exceptions in init_reader

dexter has uploaded this change for review. ( https://gerrit.osmocom.org/c/pysim/+/34697?usp=email ) Change subject: transport: do not catch exceptions in init_reader ...................................................................... transport: do not catch exceptions in init_reader We currently catch any exceptions that may occur when the card reader is initialized. Then we print the exception string or the exception type when no string is available. However, a failure during the reader initialization is usually a severe problem, so a traceback would provde a lot of helpful information to debug the issue. So lets not catch any exceptions at this level so that we get the full backtrace.
