Add get_scale definition to GRIBDatasetsExt

Same as for ZarrDatasetsExt. Needs a test with a grib file.

all the segfaults from GDAL, lol...

Aah it's GDAL warp segfaulting I was hoping it would just go away

@visr do you have an idea what's going on there? Has anything obvious changed in the GDAL side?

Hmm strange. The GDAL build was broken last week: JuliaGeo/GDAL.jl#179
So two new builds were released: https://github.com/JuliaBinaryWrappers/GDAL_jll.jl/releases
It looks like you are on the latest release. Can you easily try 301.901.201? Then we could narrow it down. The GDAL 3.9.3 release that came out today also lists two gdalwarp improvements, though this looks more like a regression: https://github.com/OSGeo/gdal/blob/v3.9.3/NEWS.md

We should also fix the Rasters.jl GDAL.jl integration tests again. I haven't looked at them much since they've been red since the beginning.

So it seems from #806 that GDAL_jll v301.901.201 works ok but v301.902.200 segfaults on gdalwarp, but otherwise seems functional?

[rafaqz]

Yeah, all the other GDAL tests are passing.

[visr]

Might be a GDAL issue then, not a build failure. Though you could still try the latest GDAL patch release that came out today in the GDAL_jll. Not sure which of the gdalwarp tests is segfaulting. GDAL.jl does have a basic gdalwarp test as well, not as many variations as Rasters.jl though.
