The first version of the package just had data from Washington,
called forested. The second release of the package also
includes data from Georgia. The forested data is the same
as it was, and now is aliased as forested_wa. The data from
Georgia is called forested_ga. The Georgia data has the
same structure, except is missing the northness variable
due to issues with the source raster. forested_ga also
includes a new variable county (#18, h.t.
@graysonwhite).
forested and its alias forested_wa
gained a new variable, county (#14).
