Add `ClosestPoints` trait which returns the two closest points between two geometries. about geo HOT 5 OPEN

I believe we only have the ClosestPoint trait, which is not (currently) implemented for Polygon x LineString, only for { Geometry } x Point.

I've updated the title of this issue to reflect the work that would need to be done - hopefully I'm understanding correctly.

Thanks for the quick reply! ClosestPoint would sort of do it; I overlooked it because the docs said Find the closest Point between a given geometry and an input Point. even though it's more general.

If it were implemented for LineString vs. Polygon, it would solve my problem. I'd have to call it twice to get both the points though, and it would do the calculation twice. Maybe a ClosestPoints trait, returning a tuple, would be appropriate? ClosestPoint could then just be a blanket implementation that calls through to ClosestPoints.

Oh right, I overlooked that you wanted both points. Your proposal seems reasonable to me.

Now we just need some bright eyed contributor to manifest it. 🤔

Normally I would, but I'm already spread too thin. I was hoping it was already implemented somewhere and I just overlooked it. I'll write my own implementation and paste it here as a starting point if someone wants to integrate it.
