proj.h adoption status

This page tracks the PROJ API status of downstream projects. With projects.h removed from PROJ in version 6 and proj_api.h scheduled for removal in version 7 it is important to have an overview of projects that are still depending on deprecated APIs. Because packaging systems and most users use releases, but fixes are made in the development version, cells contain two values. The first is for the most recent formal release, and the second for the tip of master/trunk.
