Can you add library to conan center?

I can add conanfile.py later this week, but I don't want to mess with ConanCenter's CLA signing. So, if you're really interested in it, you can freely contribute to ConanCenter yourself. Otherwise, you can just copy the clc.hpp file to your project since it's just a header-only library
