@bitner I think this addresses everything I really wanted to get done. If it all makes sense, I can do an actual release of it.

@eseglem this looks awesome! thanks for all your work on this. I did notice one thing that I made a PR to the develop branch, the alternate syntax for MULTIPOINT that does not use internal parens was not supported.

@bitner looks like I wrote the GH action correctly, and published this out as v0.2.0 now. Might have a few more tweaks I play with, for performance, but at least have a version to pin with now.
