Balancing bits

By suggestion on the GitHub issue tracker by user dbwarrior1975, we added a simple but IMHO neat feature on the Voltage Heatmap screen. If a cell is being balanced the voltage is shown underlined. This is much more intuitive than the hex values on the Tech Charging screen.

However there is no clear known mapping between the bits in the balancing information and the cell numbers. Some help here would be appreciated. The indications may be horizontally or vertically mirrored, or possibly worse. Any feedback is appreciated. I expect the highest voltage (more red) cells to be balanced more.
