Reuse iterates in TaskTable.run if hyper_param_choices contains choices that differ only in the number of iterations of an IterativeReconstructor.
Add StandardIterativeReconstructor.
Fix for save_iterates and save_iterates_measure_values that did not use save_iterates_step correctly (bug in CallbackStore that is now fixed in ODL master, but not in the latest stable release yet).
