Custom UV Pin node in Python

Maya 2020 onward has a fun useful node called "uvPin" that is supposedly useful for creating rivets. However it does not work if you're stuck on a project that uses older versions of Maya (lots of studios still using 2018-2019 versions, for example), and it feels like it might be just a bit more complicated than some applications need.

For that, as well as an exercise in creating custom nodes, I tried to write my custom broUVPin node in Python!

And it's going to be included in future releases as well!
