Title: Normalize option for PointStackerProcess

Adds an option to the PointStacker RT to add columns that normalize the count columns against their maxima. So the the highest count gets a proportion of 1.0, and a stack with a count half the maximum gets a proportion of 0.5, and likewise for proportionUnique and countUnique.

This allows for symbologies that adapt to wide variances in the size/density of a data set. For instance, when a full yer of data might be queried, or just one day.
