SQLite improving performance with pre-sort

- Random data (e.g., 160-bit random values) causes slow SQLite inserts due to B+ tree thrashing.
- Sorting data before insertion improves performance by 2-3x by enabling sequential writes.
- Comparison uses the first 8 bytes of a BLOB as an unsigned long to match SQLite's ordering.
- Batching data allows optimizations like pre-sorting for unordered primary keys.
