The library we are using from clearspring implements a series of streaming
algorithms. We are only using HyperLogLog and CountMinSketch to estimate count
distinct and heavy hitters respectively. As far as I could see fastutil is used
only in the implementation of a separate streaming algorithm to track
histograms (QDigest). Since we are not using this particular algorithm, it
should be ok to exclude fastutil from the dependency.
