IceCreamDebugger now ignores exceptions in formatting

When using icecream with multiprocessing, I had this exception. So I simply added a try-catch-print to Icecream to avoid breaking the program when something unexpected happens, as the results of the print are for debugging purposes and don't change program behavior anyway.

This exception interrupted a longrunning computation, so I believe my PR is quite useful.

Traceback (most recent call last):

@gruns Can you merge this in? I just had another run interrupted because I was editing the source code of my program (while the code was running) and icecream fails if it cannot parse the source code.
