HyperLogLog changed to use anyelement parameters (polymorphic functions),
so now it should handle all data types.
Adaptive estimator changed to use anyelement parameters (polymorphic functions),
so now it should handle all data types.
Bitmap estimator changed to use anyelement parameters (polymorphic functions),
so now it should handle all data types.
LogLog estimator changed to use anyelement parameters (polymorphic functions),
so now it should handle all data types.
PCSA estimator changed to use anyelement parameters (polymorphic functions),
so now it should handle all data types.
Probabilistic estimator changed to use anyelement parameters (polymorphic
functions), so now it should handle all data types.
SuperLogLog estimator changed to use anyelement parameters (polymorphic
functions), so now it should handle all data types.
Improved handling of types (proper handling of typlen / typbyval parameters.
This fixes precision of PCSA / Probabilistic estimators for some reason.
