Addresses the color strategy change to the argument list for `SCMeshTexturing.reconstructMesh` by adding a new method which takes the coloringStrategy as an argument. The original method defaults to `vertex` to preserve backwards compatibility.

Also adds this coloring strategy to `ScenePreviewViewController` which is the public-facing UI to SCMeshTexturing.
