METRON-637: Add a STATS_BIN function to Stellar.
When passing parameters to models, it's often useful to pass the binned
representation of a variable based on an empirical statistical distribution,
rather than the actual variable. This function should accept a set of
percentile bins and a statistical sketch and a value. It should return the
index where the percentile of the value falls.
For instance, consider the value 17 who is percentile 27. If we use 25, 75,
95 to define our bins, this function would return 1, because its percentile,
27, is between 25 and 75.
