What's the reason for the duplication of the data in voronoi.vectors?

[vchizhov]

Why does voronoi.vectors duplicate the rays on the hull? It should be enough to just store a ray once per hull edge, then we can access the rays at hull vertex i through hull[i] and hull[i+1].

EDIT: In fact the description An Uint64Array [vx0, vy0, wx0, wy0, …] is misleading, as instead it is a Float64Array, and the rays are not even quadruples per vertex, instead it seems like the construction of the rays simply does redundant overwrites of possibly previously filled in rays.

I'm not sure how to answer your question, please feel free to send a PR with optimized code. And I've now fixed the mistake in the README, thank you for the report.
