Fix regression introduced in previous release

Add functionality to find the location of a root from a linear fit to the values on a simplex.

The regression introduced before wasn't caught by the tests because the objective functions was simplex x[1] + im * x[2] - root so that the vertex positions were the same as the values.

THIS IS BUGGED. Can't discern roots form poles in 1D

Although it's possible to discern a root from a pole in 2D, it is not in 1D. It's only possible to tell whether a root or a pole is there or not. Hence the returned winding number is an unsigned int in 1D.
