  1. Added function to get accumulator for the channel. Attributing weird … 

    …Vpower measurements to explanation in the datasheet: product is taken using signed numbers for vbus and vsense and chip uses more bits than the reported vbus and vsense values.

  2. Fix byte ordering problem when block reading for 2 byte values. Will … 

    …need to fix this for other block reads as well. This correctly yields the bus values now.

    … sure our Rsense resistors are 0 ohms, so I'm keeping full scale current at 100mV. Not sure how much current to look for.
