18733	Add support for PROJ datum grid CDN	sebastic	team	"The josm Debian packages depends on proj-data for the grid files it provides (#14422).

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 GeoTIFF 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			projection grid geotiff
