Integrated group/cluster lenses based on catalogs in the LensPop interface

[furcelay]

Implements a new class ClusterCatalogLens that stores a catalog of lenses based on a group or cluster catalog. This requires two astropy tables: one for the cluster properties, and one for the members, along with a list of galaxies from the SkyPy pipeline.

This class assigns a NFW halo to each cluster based on the richness, and a EPL subhalo to each cluster member by choosing a SkyPy galaxy with similar magnitudes and redshift.

I've also updated the cluster_lens.ipynb notebook to include an example of usage.
