JuliaGeo interoperability

Using the YAXArrays.jl package with the Zarr.jl backend I am able to open both the planet-fusion.zarr/ as well as the GLDAS_NOAH025_3H.zarr data.
The bounds information is currently ignored. See YAXArrays for the details.

The CRS information is only stored in the metadata but not properly read into a CRS type.

We can also save the data back to disk but since we discard the bounds information the bounds are lost.
