This is a major release with some API-breaking changes
- Common sorted view used by all quantiles sketches with simultaneous support for both inclusive and exclusive modes
- The default mode for all methods for querying quantiles sketches was changed from exclusive to inclusive
- The mode is now a method parameter, not a template parameter
- Queries of empty quantiles sketches such as get_rank() and get_quantile() will throw an exception now (returned NaN for floating point types before)
- SerDe was removed from class templates and added to the relevant method templates (such as serialize and deserialize)
- Support for comparator instances in quantiles sketches
- Support for equality operator instance in frequent items sketch
- Added operator-> to iterators over quantiles sketches
