Windows 3.12 tests are failing

[davidorme]

Describe the bug

The tests across multiple PRs are failing on CI for Windows with Python 3.12. For example:

https://github.com/ImperialCollegeLondon/virtual_ecosystem/actions/runs/11271229156/job/31344168042?pr=583

My first guess here is that we have inconsistent NetCDF file formats in our example_data/data directory:

➜  data git:(develop) ✗ for f in *.nc; do
for> echo $f  
for> ncdump -k $f
for> done
example_climate_data.nc
netCDF-4
example_elevation_data.nc
netCDF-4
example_litter_data.nc
netCDF-4
example_plant_data.nc
64-bit offset
example_soil_data.nc
netCDF-4
example_surface_runoff_data.nc
netCDF-4
example_topofcanopy_radiation.nc
64-bit offset

I think it is choking on those NetCDF-3 64-bit offset files. Or at least that's what I'm going to try and fix first
