Adds a scalar type with random blinding. It implements `Invert` using Stein's algorithm which runs in variable time, but masks the value first with multiplication. This is useful for embedded devices where it can save the full cost of an inversion. https://link.springer.com/article/10.1007/s13389-016-0135-4
