Add a voltage reference #32

A voltage reference could improve the 32u4 measurement of the battery voltage as the battery drops out. It would also make it easier for people to hack in an RTD or other device that requires a voltage divider.

This can be just a footprint that is unpopulated.

This could be used on a different ADC. https://github.com/PaxInstruments/t400-electronics/issues/34
