[boost] [container] New container proposal: boost::container::hub, request for endorsement

Hi, I've been writing and benchmarking (candidate) boost::container::hub, a nearly drop-in replacement of C++26 std::hive that has excellent performance: https://github.com/joaquintides/hub/blob/develop/README.md#performance (The reason I didn't name it "hive" is because hub is not 100% conformant to std::hive spec, details at the repo linked above.) Is there interest in having this in Boost? If so, please endorse the submission! As the codebase is fairly small (single 1800-LOC header), and due to the subject matter, my inclination is to propose it as part of Boost.Container rather than as a separate library. Happy to discuss this proposal and its technical details. Looking forward to your feedback. Best, Joaquín M López Muñoz
