* Iris now makes better choices of dask chunk sizes, when loading from netcdf
files: If a file variable has specified, small chunks, Iris will now choose
dask chunks which are a multiple of these, up to a default target size.
This is particularly relevant to files with an unlimited dimension, which
previously could produce a large number of small chunks.
In addition, Iris now takes its default chunksize from the default configured
in dask itself, i.e. `dask.config.get('array.chunk-size')`.
