Fix warning by using our factorial2 wrapper

[tovrstra]

This PR solves a SciPy warning due to the deprecated use of the factorialk function. The solution is to use our factorial2 wrapper. See #313 for the bigger picture.

I'm planning to YOLO-merge this on Thursday, June 13 unless reviewed earlier.
