[PROJ] Which forms of TIFF compression are used for the CDN grids?

[Even Rouault]

Hi Sean,

This is actually documented at 
https://proj.org/en/9.4/specifications/geodetictiffgrids.html: "Files 
hosted on the CDN will use Compression 
<https://www.awaresystems.be/imaging/tiff/tifftags/compression.html> = 
DEFLATE or LZW" . I've also just verified that the reality matches the 
documented statement. We only use DEFLATE.
