Title: ENH: RSL no longer a required dependency

The NASA TRMM RSL library is now an optional dependency when building, installing and running Py-ART. If RSL is not installed (which is determined automatically during the build process) a warnings is issued (which can be caught and turned into are error with python -W error) informing the user of the reduced functionality and what can be done to fix this issue (install RSL and have the RSL_PATH environmental variable point to the correct location).

Longer term we can re-examine if this warning is necessary. Until dealiasing can be performed with RSL the warning will be in place.
