Extend software to compute not just wattage but watt-hours #414

At present our software output the "average wattage" so we can no the heat efficiency (that is, insulating effectiveness) of the incubation chamber, from which battery life can be predicted. An easy improvement will be to add the actually watt-hours used since the system was turned on. A user will probably no (although, granted, it is confusing) the amp-hour rating of the power bank they use at full charge. The watt-hours and amp-hours are tightly correlated.
It would be nice if the watt-hours (or amp hours at 12 volts) were printed on the OLED display, to allow the user to know how much charge may be left on the battery.
