Is it possible to extract external lut file information from the Python API?

[adalast]

I am working on a scene parser in Houdini and I know I can use the OCIO environment variable to grab the config file, but some users are using external LUT files in their pipeline as well and I am not sure how to reliably detect the LUT files. I can always just parse the config file, but I would really rather not do that.

Ideally, a feature request for a Config object member function which returns a list of the paths to all files associated with the config would be AMAZING, but I would settle for just any way to retrieve the LUT files from within the API.
