Include operational parameters in RamanFiber to_json method
Include operational parameters in RamanFiber to_json method

Currently, the RamanFiber class does not implement its own to_json
method but inherits it from the parent Fiber class. This means that
operational parameters (temperature and raman_pumps) are not included
(and therefore not picked up by the network_to_json method in
json_io.py). So if a user saves the topology, e.g. using the
--save-network option, and later uses that saved topology as input,
the result will be wrong.

This patch includes the operational parameters in to_json.
