[boost] Formal review request for Hash2

I'd like to request a formal review for the Hash2 library https://github.com/pdimov/hash2 https://pdimov.github.io/hash2/ (by Christian Mazakas and myself.) The library implements an extensible framework for implementing hashing algorithms that can support user-defined types. Its structure is largely based on the paper "Types don’t know #" by Howard Hinnant, Vinnie Falco and John Bytheway. https://www.open-std.org/jtc1/sc22/wg21/docs/papers/2014/n3980.html We're looking for a review manager. Comments and questions are welcome; you don't need to wait for the review.
