Hyperpb: Faster dynamic Protobuf parsing (buf.build)

Really missed a great naming opportunity with "superpb" (pronounced as "superb").

Interesting approach using a JIT compiler. It says compilation is slow, is there a way to persist the compiled code and load it later (for example for CLIs or faster redeployments)?

See also the discussion on the technical description last week: https://news.ycombinator.com/item?id=44591605

(IMO much more interesting article than this announcement, and that probably should have gotten more attention than it did.)

The delta to the performance of C++/Rust Protobuf implementations would be interesting.
