In the Threshold command we should support threshold methods that automatically exclude both low and high values.

(Statistics-based threshold methods could exclude outliers based on mean and standard deviation or else median and quartile ranges.

Lee K. tried an approach of finding the median to split the image in two and then using the Otsu algorithm to find low and high thresholds from the two halves.)

Requires a refactor so that ThresholdMethod deals with the entire image and there is a base class for histogram threshold methods.
