Improved exception handling

[jacione]

Cohere seems to handle most exceptions by printing that something happened and then just trying to power through. I think in many cases it would be better to let it crash so that you can at least get a traceback.

This would make sense in a single reconstruction case, also multipeak.
For GA the cohere starts with multiple processes and if one is not successful, it gracefully closes this process and continues with the rest.
The verifier is supposed to catch problems with the configuration. We need to add verification for mp parameters.
Besides the incorrect parameters, other problems can happen. We can print the exception text in addition to the print that is currently there.
