bea api

[knaaptime]

the bea api could replace some of the tables we store internally to map states/counties to msas/regions. There are tradeoffs to that, obviously. The tables themselves are quite small, so they can be read directly with a pd.read_csv, just like we already do with the inflation table. The difference here is that the tables from BEA are formatted a bit differently than the ones we're using currently, so it would either require some reformatting on read, or require a "breaking" change
