Move _url_paths() method to BaseDatasource

A datasource method to load the ``url_paths.csv`` file was
being used for Arkansas, Ohio and West Virginia and
will likely be needed by other states.  Move Arkansas' implementation
to ``BaseDatasource`` and remove the duplicate implementations from
the other states' datasource implementations.
Cache jurisdiction mappings, add _counties utlity method

In Iowa, we'll have to iterate over the list of counties multiple
times.  We should cache the jurisdiction mappings instead of
loading the jurisdictions from files each time.

Also add the ``_counties()`` utility method to ``BaseDatasource``
as getting just the counties will probably be a common needs.
Add _standardized_filename() method to BaseDatasource
