Implement timing ranges for multiplication/division

[hintron]

After reviewing the simulator reference code in #25, the manual has min and max values for multiplication and division, rather than just a single timing value. So I should add in a "max" value. Do I print both? Probably. I could take the max and add it to the total clocks. Alternatively, I can take the average, rounded up, and add that to the total.
