Add function to calculate Z-scores to find outliers to statistics in kernel. Already used in GetDetOffsetsMultiPeaks and SortHKL, so put function calls in these algorithms. Add function for Modified Z-score to test if this is better.

Tried Modified Z-score in both CalibrateRectangularDetector and calibration was better with original Z-score. No difference in SortHKL. Both still use original Z-score.

The calculation looks correct from inspection, but there should be unit tests - ticket #5706 created for that.
