Title: Add visitor access methods, parse the response into a hash, and convert dates into their expected format

Merge request for the following items:

* implement visitor access methods (visitors_by_site_id and visitor_by_id)
* parse the response into a hash (so that attributes can be access like site['site_token'])
* convert date parameters into their expected format for methods that expect them
