We have libyaml/0.2.5 and py-pyyaml/6.0.2 in spack-stack-2.1 / develop. Do we really need another yaml library? What does it provide that the others don't?

yaml-cpp is used by two new planned components to the WM: CATChem and CECE. ESMF also builds an internal version and could use the external. libyaml is C-based, which is not as programmer-friendly for C++ applications. In general, it would seem better to have the libraries share a single yaml-cpp build rather than compile their own copies or fetch from external sources.
