Updates to importer to support other table types.

[delucchi-cmu]

Includes:

• catalog type in parameters
• test data for a source catalog
• fixes to map reduce to stop creating so many index columns
• adds columns to output so data is later readable easily as a dask dataframe (Norder, Dir, and Npix)
• write out the hipscat index field
• increases to test coverage

Closes Issue #48
