Add API call to validate addresses

This adds support to the API module for performing address validation
lookups. It doesn't hook anything up to that, but you can now call:

SuperGood::SolidusTaxjar.new.validate_spree_address(address)

to hit the TaxJar address validation API and a list of validated
addresses back.
