Cloud data is changed in the data repo v1.9

[RobertPincus]

@sehnem There is a new release v1.9 of data related to cloud optics.

There are now two sets of cloud optics files - one defined by g-point and one defined by bands, which need to get broadcast to the g-points in all-sky applications. You can tell them apart when the files are read because the files defined by bands (as the original files were) do not contain a bnd_limits_gpt dataset in the netCDF files.

Note that the reference results have also been updated, even for the all-sky computations with clouds defined by band.
