"NE MLK Jr Blvd" is parsed incorrectly

[ezheidtmann]

The short_name of this OSM way is "NE MLK Jr Blvd" -- https://www.openstreetmap.org/way/418650741

It's short for "Northeast Martin Luther King Junior Boulevard".

And usaddress does a great job on the latter, but appears to consider "MLK" a "PreType":

Dozens of US cities have a street named "MLK Jr" and I imagine this abbreviation is common. Let me know what I can do to help improve results here.
