vcpkg release ; request to use `#include <ed25519/`

[SamuelMarks]

I created a vcpkg port for you.

https://github.com/microsoft/vcpkg/pull/35143

The dependent library that uses your project needs some stuff from fe.h, fixedint.h, and ge.h. Any chance these can be put under the ed25519 namespace, as #include <ed25519/fe.h> &etc.?

Thanks
