PROJ 7.0.0

The major feature in PROJ 7 is significantly improved handling of gridded
models. This was implemented in RFC4.
The main features of the RFC4 work is that PROJ now implements a new grid format,
Geodetic TIFF grids, for exchaning gridded transformation models. In addition
to the new grid format, PROJ can now also access grids online using a data
store in the cloud.

The grids that was previously available via the proj-datumgrid packages are now
available in two places:

1. As a single combined data archive including all available resource files
2. From the cloud via https://cdn.proj.org

In Addition, provided with PROJ is a utility called projsync that can be used
download grids from the data store in the cloud.

The use of the new grid format and the data from the cloud requires that
PROJ is build against libtiff and libcurl. Both are optional dependencies
to PROJ but it is highly encouraged that the software is build against both.

WARNING: PROJ 7 will be last major release version that includes the proj_api.h
header. The functionality in proj_api.h is deprecated and only supported in
maintenance mode. It is inferior to the functionality provided by functions
in the proj.h header and all projects still relying on proj_api.h are encouraged
to migrate to the new API in proj.h. See https://proj.org/development/migration.html
for more info on how to migrate from the old to the new API
