getProcessor() method on Baker interface?

[dbr]

I think being able to get the processor for a given Baker instance would be useful - e.g to generate a preview of the given LUT, or to get the cache-ID for a given transform to see if a LUT needs to be rewritten or not

(this was based of the PyOpenColorIO wrapper - I didn't check if such a method exists in the C++ API)
