v2.2.0 SurrealKV benchmark performance

[alfalcon90]

Thank you for all the hard work on getting benchmarks out and the v2.2.0 release. I'm really happy to see the change in strategy towards stability and performance.

I noticed in the benchmarks that SurrealKV seems to underperforming RocksDB by quite a bit in most cases. Is the goal with the change in strategy to address that? Do you foresee SurrealKV performance catching up and surpassing RocksDB/PostgreSQL in the long-term? I'd love to hear any thoughts the team has on that.
