Address mismatch in geo*

[chiouey]

proposed changes

• data(geocoded_cached) has addresses that don't always align with address data in newer files

  • use multiple variations of address as keys to match: replace "avenue" with "ave" etc.;
  • only use 5 digit zips instead of 9 digit.

• identify historic newark schools without an entry in the nj directory, geocode their addresses, and bind to geocoded_cached.rda

• all newark schools have wards
