This Postgres module introduces a new data type `hll` which is a HyperLogLog
data structure. HyperLogLog is a **fixed-size**, set-like structure used for
distinct value counting with tunable precision. For example, in 1280 bytes
`hll` can estimate the count of tens of billions of distinct values with only a
few percent error.
In addition to the algorithm proposed in the original paper, this
implementation is augmented to improve its accuracy and memory use without
sacrificing much speed.
