out-of-order time-window buffer merging

List<UnsortedDataPoint> -> List<SortedDataPoint>

Buffer out-of-order incoming points in active, contiguous memory partitions, sorting and merging them sequentially during the disk-flush cycle.

Problem it solves

Late-arriving and jittery data points disrupt append-only storage semantics, but sorting on every write degrades ingestion performance.
