Fix sweep direction when new cartopy available
Previously cartopy did not have a way to pass in the sweep direction when using a geostationary projection. For GOES-R we need to use sweep = x for the ABI instrument (the default in the layer under cartopy is unfortunately y rather than x).
The folks working on cartopy have apparently made the fix, so when they release a new version we need to make the change in our QL to set the sweep correctly and make sure that we are able to package the program with the newer, fixed version of cartopy.
