stats: Add the interquartile mean (IQM)
https://en.wikipedia.org/wiki/Interquartile_mean
The IQM is a truncated mean and so is very similar to the scoring
method used in sports that are evaluated by a panel of judges:
discard the lowest and the highest scores; calculate the mean
value of the remaining scores.
It's useful to hide outliers in measurements (due to cold cache etc),
without having to worry too much about the actual distribution.
