§HyperLogLogPlus
hyperloglogplus module contains implementation of HyperLogLogPlus
algorithm for cardinality estimation so that [crate::series::approx_n_unique] function can
be efficiently implemented.
This module borrows code from arrow-datafusion.
§Examples
let mut hllp = HyperLogLog::new();
hllp.add(&12345);
hllp.add(&23456);
assert_eq!(hllp.count(), 2);
