Exceptions in frontend are silently discarded and not handled

[twam]

Any exceptions frontend are silently discard and not handled.

The issue is most likely that self._pipe_recv_frontend_exception defined in https://github.com/usb-tools/ViewSB/blob/51c85aa483277d098658dbff809c2cbd982fa59e/viewsb/analyzer.py#L62 is nowhere used.

Yes, process_analysis_queue should be handling these.
