updated calibration FIXED INCORRECT VCC ON WIRING
IMPORTANT was adding up average counters 4x too often
IMPORTANT tracking is rounded to 1mW to remove noise
make analogWrite begin near transistor threshold VgsOn instead of at zero
added MINWATT to behave right at beginning of curve
MPPTTIME of 25 still yields more than ten averaged wattage readings per cycle
IMPORTANT it seems that arrays can't be initialized to a single value as i had thought
introducing mode, which has bits for enabling MPPT and tracking
