[WIP] Maps overhaul

[DonIsaac]

Relies on #217.

Adds a ton of new fields for the buildings table, including

• city
• state
• zip code
• full address
• address number
• street name
• more to come after reports scraper is written)

Also adds a bunch more buildings that were not in the database already.

CONSIDERATIONS (IMPORTANT)

A lot of the building data is now sourced from UMD Facilities Dept. One source is their ArcGIS database, which powers maps.umd.edu. You can find it here.

1. We may need written permission from them to distribute this data. Yes, it's technically publically available. Yes, we are currently extracting building location information. But they explicitly state that we need permission, and I don't think we should poke the bear.
2. There is a lot more data available from this database than is currently being extracted, such as restaurants, coffee locations, parking lot info, gender-neutral bathrooms, etc. etc (peep these tables for a taste). We could add this if we want. Doing so may have implications for the above point.

TODO

• finish scraper for reports csv
• test coverage for new scraper capabilities
• write database migration to update old databases
• contact umd facilities, get approval for ArcGIS data use
