Clean up PROJ mess

[Nils Breunese]

You could already create a proj9 port now and have proj depend on that. When version comes out you can add proj10 and change proj to depend on that instead of proj9. This way users can choose to install ‘proj latest’ or ‘proj 9’ explicitly, with the former getting updated as newer versions are released, and the latter just giving a user version 9.
