Census County Subdivision data now generally available

Today, we added support for Census County Subdivisions with the Census field append.

County Subdivisions are either Minor Civil Divisions (MCDs) or Census County Divisions (CCDs) depending on the state.

Here's an example of the Census County Subdivision returned for "1600 Pennsylvania Ave NW, Washington DC"

"county_subdivision": {
    "name": "Washington",
    "fips": "50000",
    "fips_class": {
        "class_code": "C5",
        "description": "An active incorporated place that is independent of any county subdivision and serves as a county subdivision equivalent"
    }
}

Census County Subdivisions are available in the spreadsheet upload tool as well as the Geocodio API.
