chore: add constructor for TSPRandomInitializer

fix: iterate city positions by rows

refactor: use swap_rows in SwapPerturbaiton instead of swapping by indices

feat: add plotting of TSP

feat: add utilities to perturbation to iterate through wrappers easily

Make PerturbationOperator implement Any, allowing it to be downcasted.
Make WrapperPerturbation for perturbations that wrap other
perturbations, such as the mutation perturbation and bounded perturbation.
Make ListWrapperPerturbation for pertrubations that wrap multiple
pertrubations, such as the combined perturbation.

This should allow for easily looking through perturbations, finding
all perturbations of a specific type and modifying them. One use
case can be for changing the probability of a mutation perturbation
during evolution.

chore: do not pass pairing as mut

tests: tweak one_max parameters

refactor: abstract pairing to n-ary
