ipa: rpi: histogram: Add interBinMean()
Add a new helper function Histogram::interBinMean() that essentially replaces the existing Histogram::interQuantileMean() logic but working on bins instead. Rework the interQuantileMean() to call into interBinMean() with the appropriate convertion from quatiles to bins.
