Flag to output .pklz crash files

[Shotgunosine]

When debugging MRIQC sometimes it would be helpful to be able to reinstatiate the objects and interact with them via the nipypecli. It'd be great if there was a flag in MRIQC that would change the crashfile output format to pklz. @oesteban pointed out that this is the line where that option is set:

Yay, thanks for taking a look at this again!

This should be easier after #834 is implemented.
