Adding a custom vcpkg port for correlation vector.
That way we don't have some dependencies coming from vcpkg and others from FetchContent.
Can be made simpler in the future by consuming from the central vcpkg registry (https://www.github.com/microsoft/vcpkg/pull/37282) but I'm accelerating the migration here by copying the portfile. To do in #135
