Title: Displacements in fitting result

This PR adds the `displacements()` method in the `FittingResult` class. This method returns the displacement between each iteration's shape and the precious iteration's shape. It can either return the mean, median, min, or max displacement (point-to-point euclidean distance) or the displacement of a specific landmark point.
