Still using a single io engine, so little benefit.

61de3f9287 [thin_metadata_pack/unpack] Replace C++ implementation with a Rust one.
The Rust implementation is multithreaded, performs better in general and
does custom compression of btree nodes to achieve much better compression
ratios.  unpack also checksums expanded metadata to validate it.

Format version has jumped to 3, no backwards compatibility, but I think
that's ok since we never made a release that contained the C++ version
of these tools.

Benchmarks

On an 8 core, 16 hyperthread machine.

Rust      70M         1.4s          1.8s (verify)

metadata 16G, sparse:
