Wrong centroid calculation

[raviqqe]

import { centroid, polygon } from "@turf/turf";

console.log(centroid(polygon([[[-1, -1], [1, -1], [1, 1], [-1, 1], [-1, -1]]])));

The result should be a point at (0, 0) but is actually (-0.2, -0.2). The algorithm is using the enclosing point twice.

Great pickup thanks @raviqqe

I'll get a fix for this within the v7 branch and add a test.

This is probably in development, but I just made a Fiddle using 7.0.0-alpha.1 and the centroid still seems off: https://jsfiddle.net/9z37srjb/3/

Yeah the change hasn't been released yet @vomc , it was added after the 7.0.0-alpha.1 release
