+20-30% throughput on UpdateColumnarStatistics benchmark (with large statistics enabled)
- Do not factor in value.Id when calculating column digest
- Pack metadata directly instead of multiple HashCombine calls
- Use SplitMix64 finalizer for proper bit distribution
- Use cheaper xor with metadata instead of HashCombine
- Use XXH3 for strings
- Remove unnecessary copy
- Measured quality increased: on 20 (c=1..20) sequences `{nc | n \in [1..10^6]}` MAE dropped from ~36% to ~20%
HLL digests might temporarily suffer a 2x increase upon merging with the previously computed ones.
