Fix type annotation in run() method of Simulation() class. (#423)

* Fix type annotation in run() method of Simulation() class.

* Update type annotation to adhere to **kwargs annotation style. Add info to docstring.

* Keep linter happy.

* Add QuTiP docs for simulation options to docstring.

* Use shortened URL for QuTiP link.

* Fix rendering issue of hyperlink by including newline.
