Dedupe exact address matches between OA and OSM

[pnoll1]

There are areas in Europe that don’t suffer from expanded address issues and have high address coverage in OSM.

Looking for exact matches would bring down file sizes, clean up search results and be building blocks for future deduping.

• [x] pull addresses into Postgres using osm2pgsql
• [ ] Abbreviate Osm addresses and streets
• [ ] Dedupe with OA data
• [ ] Remove addresses from osm extract
• [ ] write to OSM file
• [ ] Merge with area data
