Title: Support multiple buckets for a single dimension

This is a thing that I worked on at home that I'm merging now before I lose commit privileges on datacube.

This removes a previous limitation where each dimension of an input point could only be assigned to a single bucket. Now a single input dimension can be assigned to multiple bucekts.

For example, suppose you're counting Twitter tweets and you want to count the occurrences of a particular hash tag. When you bucket a tweet in the "tags" dimension, you could return multiple tags, each as its own bucket. Previously, only one bucket would have been allowed for each dimension.

Attn @timrobertson100, this is the feature I mentioned in my email the other day that should help with your taxon counting.
