Joe Thornber 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.
