Returns the PROJ search paths that GDAL's PROJ contexts are using, whether the copy of PROJ data bundled with vapour (if any) is active, and the metadata of the proj.db that resolves first on that path.
vapour_proj_data()a list with elements 'search_paths', 'bundled_active', 'proj_version', 'proj_db', and 'message' (the startup message explaining why a bundled copy was ignored, or NULL)
