Feature request: show iteration count of total and current iteration rate

It would be very useful to have an option to display the actual current number of iterations completed out of the total, instead of just a percentage. It would also be nice to print the current rate of progress as iterations/second or seconds/iteration, similar to Python's tqdm package.

As a remedial measure one may use the kwarg showvalues with a Channel or a RemoteChannel to display the number of iterations
