Summary

Address suffixes commonly have many different forms, normalizing these suffixes during our validation phase will improve scores.

Acceptance Criteria

• A new Address.line validation function to normalize suffixes
• Update site/reference.md to indicate ADDRESS suffixes are being normalized

Details / Tasks

When parsing address lines, normalize all suffixes using the USPS street suffix map. For example, 12 Main St, 12 Main St. and 12 Main Street should all be normalized to 12 Main ST.
