to_points

[LanaLubecke]

In the utils.jl file, the function to_points is not working properly. In addition to fixing it, it would be helpful to add an optional argument "repeat_last" which is a boolean. This boolean would specify whether or not to_points returns an array where the first and the last point are the same or not. If "repeat_last" = true, then if the first and last point are not already the same, to_point adds the first point again to the end of the array.

Sounds good to me

It looks like collect(flatten(GI.PointTrait, GO.tuples(geom))) has superseded to_points? We can implement it in that form if it's easier.

There should be a faster way that avoids the rebuilds in tuples
