[PROJ] PROJ 8.0.0 and PROJ-data 1.5

[Kristian Evers]

On behalf of the PROJ development team I am happy to announce the
release of PROJ 8.0.0 and PROJ-data 1.5. 

The PROJ release includes a number of updates and bug fixes as well
the removal of the proj_api.h header file. See the detailed release
notes below. 

The PROJ-data package adds two new grid files (NN1954 and NN2000)
that are referenced in the database updates. NODATA values has been
clarified in a few Danish and Norwegian grids.

8.0.0 Release Notes
-------------------

With the release of PROJ 8 the proj_api.h API is finally removed. See
https://proj.org/development/migration.html for more info on how to migrate
from the old to the proj.h API.

With the removal of proj_api.h it has been possible to simplify error codes
and messages given by the software. The error codes are exposed in the API.

Several improvements has been made to the command line utilities as well as
tweaks in the underlying API.
