Style-dictionary: Add an advanced example with the gist shared by Dbanksdesign about CTI structure

[didoo]

In a thread on Slack @dbanksdesign shared this gist:
https://gist.github.com/dbanksdesign/dd67b7c265b75089c03d969dceaa41f1

It may be an interesting example to add to the "advanced" examples. What do you think?

Here's my project:

I might be adding something similar to this
