Description: Provides an interface to the 'Apache DataSketches'
        (<https://datasketches.apache.org/>) library of streaming
        algorithms for approximate analytics on data too large to hold
        or process exactly. Sketches are compact, mergeable summaries
        built in a single pass over a stream that answer queries such
        as approximate distinct counts, quantiles and ranks, frequent
        items and point-frequency estimates, weighted sampling, and set
        membership with mathematically proven error bounds. Implements
        Karnin-Lang-Liberty (KLL), Relative Error Quantiles (REQ),
        t-Digest, HyperLogLog (HLL), Compressed Probabilistic Counting
        (CPC), Theta, Frequent Items, Count-Min, Array of Doubles,
        Variance Optimal (VarOpt), Exact and Bounded Probabilistic
        Proportional-to-Size (EBPPS), and Bloom filter sketches, with
        native serialization for interoperability with other 'Apache
        DataSketches' implementations.
