[Feature Request] Add "geometric mean" to categorical ordering

[acxz]

This feature request is to add the geometric mean for ordering/sorting in the categorical axes type.
In particular the addition of "geomean ascending" and "geomean descending" to categoryorder is requested.

The geometric mean is useful since when visualizing/sorting data on a log scale, the arithmetic mean can be very skewed. For larger scales like the log scale having a categorical sort on the geometric mean can provide a better ordering scheme.
