jluastro/PopSyCLE: Filter Systems, Reformatted HDF5 Files, Pipeline Execution

This release adds the abilities to add Zwicky Transient Facility photometry to the PopSyCLE data pipeline, with a structure set up for future support of additional filter systems. Additionally, hdf5 files generated by generate_pop_syn now contain the metallicity, bolometric luminosity, surface gravity, and effective temperature of stars which may be used for population selections and stellar typing. The structure of these hdf5 files have been reformatted to use numpy compound datatypes, allowing for easy user access without using the col_idx objects in previous releases. Lastly, this release allows for execution of the PopSyCLE pipeline with the command line tool run.py, as well as support to run this pipeline executor on a Slurm scheduler.
