Implement HTTP Signature Authentication

This CL implements HTTP Signature Authentication as defined in [draft-ietf-httpbis-unprompted-auth-05](

For now this is all inside the MASQUE code to allow easily testing interop at the IETF hackathon without the testing requirements that come with the main HTTP/3 code.

QUICHE stands for QUIC, Http, Etc. It is Google‘s production-ready implementation of QUIC, HTTP/2, HTTP/3, and related protocols and tools. It powers Google’s servers, Chromium, Envoy, and other projects. It is actively developed and maintained.

There are two public QUICHE repositories. Either one may be used by embedders, as they are automatically kept in sync:

To embed QUICHE in your project, platform APIs need to be implemented and build files need to be created. Note that it is on the QUICHE team's roadmap to include default implementation for all platform APIs and to open-source build files. In the meanwhile, take a look at open source embedders like Chromium and Envoy to get started:

QUICHE is only supported on little-endian platforms.
