[PROJ] PROJ 9.4.0 & PROJ-data 1.17

[Javier Jimenez Shaw]

Thank you Kristian!

https://crs-explorer.proj.org/ and https://spatialreference.org/ were also
updated to PROJ 9.4.0
Related to that, there is a trick to inspect the changes in EPSG between
PROJ releases: Check the changes in the file "crslist.json"
In this case in this commit: (load the diff of crslist.json. It is quite
large)
https://github.com/OSGeo/PROJ-CRS-Explorer/commit/99f808ad37c752b25b4d2d5bda9b3d472d578dfc
(Having those tags of crslist.json in GitHub, the webpage allows you to go
back up to PROJ 8.2.1 with a combo-box)

Yes, the diff can be large, specially if they change an area of use that
affects many CRSs. But I find useful to see the added CRSs, or some other
changes.
This time I found a few new German systems that I was not expecting (but I
was missing ;)

Notice that this is only about CRS defintions, not about transformations.

Cheers,
Javier.

PS. PROJ-data 1.17 also adds the Portuguese geoid model GeodPT08
