Leginon

Falcon3 communication is still buggy. It gets some error that we catch and handled with imagedata = None. This is normally a fatal error and we should stop pause and wait for user to check hardware. However, it appears to recover fairly fast. To prevent lost of time while no one can make it continue, we will catch the error and abort the target and move on.

I do hope this is resolve by the manufacturer before 3.4 release.
