Add expressway tagging to the transportation layer (#1313)

Browse Source 
Fixes #1148 

This PR adds expressway tagging to the `transportation` layer, by setting `expressway=1` for non-motorway roads tagged `expressway=yes`, and omitting the tag otherwise.  Additionally, I've added a few unit tests to verify that the expressway tagging is being imported and updated into the intermediate tables.

Here is an example of expressway tagging on US-1 in Rhode Island, USA:
