Yes, the tests seem to be failing since some of the code is removed from both ```irsa_dust.utils``` and  ```irsa_dust.core```.  Working on updating the test suite.  Also the ```DustResults``` class is removed.  This implemented multiple object queries.  Should this be re-implemented via the ```parallel_map``` method? All the results are then returned as a list - this would be fine for most queries but for the ```get_query_table``` ( that returns the xml response as an ```astropy.Table```), it would be more preferable to merge the query tables for each of the queried objects into a single table?
