Check added to Optimizer.pre_run_check and dynamics.save_amps
to ensure Dynamics.initialise_controls has been run
that is the initial amplitudes have been set
optimisation alg parameters max_metric_corr and opt_alg_acc_fact (now renamed accuracy_factor) now available
as parameter in the pulseoptim funcs
scale_factor for TRACEDIFF fidelity computer now available as parameter in the pulseoptim funcs. Calculated as 1/2N when None
pulse_scaling
pulse_offset also now available as pulseoptim func params
