Add logging and/or other debugging help

[kelle]

I recently encountered an error while running db.inventory on a source. As is usual with sqlalchemy, the error message was not helpful. It would have been super helpful to have the ability to turn on logging.debug for astrodbkit to get more info. We ended up adding a print statement in this loop to see that it was crashing on a new reference table which we had neglected to add to the REFERENCE_TABLE list.

AstrodbKit/astrodbkit/astrodb.py

Line 483 in 24a4749

self._inventory_query(data_dict, self._primary_table, name)

If you still have the error message, or the example, it may be useful to provide it here. But in the meantime, adding some extra verbosity doesn't hurt. We aren't (yet) using logging and that is a big undertaking, but we have other examples where we have a verbose flag that we can use.
