Is there any reason for such a big nodata margin?

I investigated it because the longitude of the top left corner was negative.

I've pushed a commit fixing the index (and ran locally the check_grid_gtiff.py script with the latest PROJ db, confirming it passes OK), and added version_added=1.23 in the .csv file

I'll merge as it for now. Given compression the margin shouldn't had that much to the file size
