Actually make hollow sphere points uniformly distributed

Since the dawn of time, our hollow sphere generator was buggy: the
points generated for hollow sphere were not actually uniformly
distributed. Rather, they were projected form a uniformly filled cube,
resulting in denser regions for projections of edges and corners.

For 3D, that could have been fixed using modified spherical coordinates
generations. However, that does not easily expand to the
multi-dimensional case. Instead, we generate the points within the
sphere, and then only project those to the surface.
