[PROJ] Update in EPSG db

[Javier Jimenez Shaw]

Hi

After adding the spanish peninsula geoid file, now there are available in
EPSG some vertical CRS to include the Canary Island grid. (Spanish IGN
requested them recently).

Their transformations are also available (one per island, also for Balearic
islands).

For instance
https://beta.epsg.org/transformation_9417/REGCAN95-to-Gran-Canaria-height-1.html

The script "grid_tools/vertoffset_grid_to_gtiff.py" needs the vertical CRS
to be there, EPSG:9397 for instance.

I am trying to create PRs in PROJ-data and PROJ to support the new grid on
every "new" vertical CRS.

How is the EPSG database updated?

AFAIK, there are other changes, like "ED50 to ETRS89 (12)" being replaced
by "ED50 to ETRS89 (16)" and "ED50 to ETRS89 (17)"

Thanks.
