18733	Add support for PROJ datum grid CDN	sebastic	team	"The josm Debian packages depends on proj-data for the grid files it provides.

With the release of PROJ 7.0.0 scheduled for March 2020, the proj-datumgrid repository which serves as upstream for the grids is deprecated in favor of the proj-data repo containing the grids in TIFF format and who are provided by the new CDN. See [https://proj.org/community/rfc/rfc-4.html PROJ RFC 4: Remote access to grids and GeoTIFF grids] for details.

JOSM should probably add support for the CDN to fetch grids on demand when it needs them and they're not locally available."	enhancement	new	normal		Core
