Title: Automated weighting function for simple SISO systems

Added function to automatically fit a third-order weight to a perturbed plant response. Currently only for SISO and assumes multiplicative uncertainty. Not designed to handle functions with peaks in the weights.
The function runs in perturbed_models as a script on the example system there.
