Add a new polygon-based simplification method to ConvexHull3, and a tolerance for the initial hull build, to support use cases where we do not need an exact hull and can prioritize using fewer plane + avoiding near-degenerate planes in the output. This simplification is especially effective for cases where a large number of near-coplanar faces would exist in the exact-hull output.

Add option to drive adding more negative space samples when the current samples don't cover the space identified by Voxel Search (and are farther apart than the target Sample Spacing), to make the negative space coverage algorithm better able to protect space in challenging cases where a smaller fixed number of samples would fail.
