Title: Added barbs method to GeoAxes.

This PR simply adds a `barbs` method to `GeoAxes` for plotting wind barbs on arbitrary map projections. It probably should have been part of #348 but I forgot about it.

I didn't see the need for anything other than a simple integration test. The test plots are a bit boring (but then so are wind barbs IMHO), colour can be added if desired.
