Downloading census tracts for 2010 is not possible when specifying a county

[pedrocamargo]

Apparently, Tiger data has different field names for COUNTYFP on census tracts for the 2010 Census, and that causes the software to fall over when one specifies the county when downloading census tract data for that year.

To reproduce the error one can run:

import pygris
pygris.tracts(state="Maine", county="001", year=2010, cache=False)

If instead you run

import pygris
pygris.tracts(state="Maine", year=2010, cache=False)

You obtain the correct data
