Add example LUT/CTF files for doing performance tuning

[doug-walker]

Under tests/data/files there are already a lot of example LUTs in many formats. However, these are mostly used for LUT file format parser tests. It would be useful to have some LUTs that are specifically recommended for performance tuning. It would be helpful to add to the documentation in the contributor guide recommending a specific set of files to use.

The existing files already contain examples of single operators but it would be helpful to have more examples of files, in CLF or CTF format, that contain multiple operators, since this more representative of a complex transform.

One file that is a useful example of a transform that uses many different operators is the heavy_transform_tetra.ctf file that was uploaded in to Slack recently: https://opencolorio.slack.com/files/U3R43KX3N/F05T30VE6G1/heavy_transform_tetra.clf.zip

I can take a look at this.

Can you add me to the slack channel so I can view the referenced chat? My email is: [email protected].

Mason, you should be able to join the slack channel yourself: http://slack.opencolorio.org/

But we are on the free Slack plan, so the file you're looking for may not be available anymore. Here's the zip file I mentioned above:

I just joined! Thank you for providing me with the file.
