Adaptive enhancements

[t-b]

• Don't do linear estimation for DASCale values when the slope is negative or zero, instead go in DAScaleNegativeSlopePercentage steps to larger DAScale values. If negative or zero with further increase in DAScale, this is the max DAScale that is acquired. Then fill in, as described next (setQC is passing in this case, independent of NumSweepsWithSaturation):
• With negative slope, fill in between last DAScale with positive slope and first negative slope DAScale based on 'DAScaleFillInPercentageNegativeSlope'
• Round to pA in SetDAScale
• Add prefix (F or R or X) in "DAScale values left" to mark where the value came from
• Add an analysis parameter to determine how many SCIs we look back for failing adaptive suprathreshold data. We currently only look at the very previous one.
