C++ HTTP Headers Hashing CLI

HTTP Headers Hashing (HHHash) is a technique used to create a fingerprint of an HTTP server based on the headers it returns. HHHash employs one-way hashing to generate a hash value for the set of header keys returned by the server. See https://www.foo.be/2023/07/HTTP-Headers-Hashing_HHHash for more info.
