[PROJ] PROJ 9.3.1RC1 & PROJ-data 1.16RC1

[Kristian Evers]

All,

It’s time for another round of releases, so in preparation for the final packages I have uploaded
 release candidates for PROJ and PROJ-data. Download the archives here:

https://download.osgeo.org/proj/proj-9.3.1RC1.tar.gz

https://download.osgeo.org/proj/proj-data-1.16RC1.tar.gz
https://download.osgeo.org/proj/proj-data-1.16RC1.zip

The PROJ release includes updates to the database contents and bug fixes. See the release notes below. 
The PROJ-data release adds the German geoid model GCG2016.

Please test the release candidates and report any issues you may find with them. Either here
on the mailing list or on GitHub.
