Description

See #332 for some related work and discussion.

The code in pyresample/area_config.py uses a lot of PROJ dictionaries where it may be able to use CRS objects. Additionally, we should allow users to provide WKT if they want. By using CRS objects internally accepting different inputs should be much simpler.
