large geos xwalk df

[davilak]

Would it be useful to have one df that had towns, their counties, their PUMAs, their metros, etc. Basically all the groupings that a town might belong to that also have GEOIDs?

The xwalk data comes from the LODES crosswalk, just as a subset of the more useful columns. That does include metro area, but not PUMA, which I could do pretty easily.
