Calculates a convex hull for an array of vertices

Usage

const convexHull = require('@deltasnare/physics2d-convex-hull')

const hull = convexHull([[0, 5], [0, -5], [2, 0], [-2, 0], [0, 2]])
// returns [[0, -5], [2, 0], [0, 5], [-2, 0]]

A function is exported in the following format:

convexHull(vertices)

Where vertices is an array of vec2 in arbitrary order. The function returns another array of vec2, which define a convex hull with all input vertices inside it. The output is arranged in counter-clockwise order.
