Updated cloud optics, correct aerosol optics, homogenized

Clarifies that ice particles sizes are diameter, not radius (#8)

Provides updated cloud optical properties by band and by g-point (#9). Files with by-band properties lack a bnd_limits_gpt dataset.

Compresses and homogenizes most netCDF files (#4) except those copied from the Earth System Grid Federation.

Corrected sea-salt aerosol optical properties.

Corrects order of data for sea salt aerosol optical properties as described in #5 .

Updated LW results for changed source function, quadrature

Update longwave examples to reflect changes to RTE code: using a single Planck source at each level and changing quadrature secants and weights

Updated all-sky results

All-sky results use analytic profiles of T, p, q. Results are provided with and without aerosols.

Non-missing RFMIP reference examples

Initial release v1.7 contained missing values for RFMIP reference results. This release contains actual values.

Aerosol optics, liquid size updates, inputs and reference outputs

Builds on data packaged with v1.6 of the RTE+RRTMGP. Includes (potentially answer-changing) updates to size limits for liquid cloud drop sizes, new aerosol optics data, along with inputs and reference outputs produced from this data.
