Add Python GPUProcessor example

[beatreichenbach]

This just adds a basic example to the docs that would have helped me find what I needed.

Fixes https://github.com/AcademySoftwareFoundation/OpenColorIO/issues/2164

I am probably going to fail EasyCLA so please feel free to edit and take over if it's easier.

edit: Is there any workaround that allows me not having to use my email address for the EasyCLA? Can I use my [email protected] address?

I'm not sure. I know for the individual CLA registration process, you have to provide legit contact information; but I think as long as github is able to validate your signed commits, you can sign with your @users.noreply.github.com address. Put it this way: whenever I use github's web interface for any git-fu, it creates commits signed with my users.noreply.github.com address that pass the EasyCLA + DCO checks. (Even though I still use the e-mail address I signed up with whenever I manually sign commits...)

Okay, I completed the EasyCLA and pushed a signed off commit. Hopefully I did everything right. Thanks for the spellcheck!
