Hi Stefan,

Thanks for your pull request - much appreciated.

To keep Grok contributions aligned with the Grok license, I am setting up a contributor license agreement for the project. Let me know if you are comfortable agreeing to a CLA.

Or, if not, I could run codespell on the project.

By the way, I have already included you in the THANKS file.

Best Regards,
Aaron
