 Returns the raw signal or the last state of the magnetization according to the value

+of the `"return_type"` key of the `sim_params` dictionary. 
+
+This is a wrapper function to `run_sim_time_iter`, which converts the inputs to the appropriate types and discretizes the sequence before simulation. The reported simulation time only considers `run_sim_time_iter`, as the preprocessing duration should be negligible compared to the simulation time (if this is not the case, please file a bug report).
