Use dask arrays in dask ufuncs to avoid nan chunking behaviour #89

Closed sjperkins closed 3 years ago

Dask ufuncs seem to produce nan chunks when given xarray DataArrays even when this shouldn't strictly happen. Use dask arrays in dask ufuncs to circumvent this.

Thanks! Going to supersede this with #90 (so as to unpin the dask version while we're at it), also because it's easier for me to test main repo branches inside containers.
