Hi,
When running in stream mode, my stream processor output this text:
2020-08-26 22:46:45 70766: bgpstream_parsebgp_common.c:594: ERROR: Failed to parse message from 'http://archive.routeviews.org/route-views.amsix/bgpdata/2020.08/UPDATES/updates.20200826.2130.bz2' (-2:Invalid Message)
.. and then stopped receiving messages. It would be good to receive this as a Python exception so that I could handle or ignore it as appropriate (and for messages to continue).
