ConversionFactor is used to scale data when reading/writing phasor values.
MagnitudeMultiplier is used when reading/writing PHSCALE values in the configuration frame.

When generating a fixed-integer IEEE C37.118-2011 data stream, ConversionFactor and MagnitudeMultiplier should be the same so that the phasor magnitudes can be scaled by the appropriate multiplier and then that same multiplier can be encoded into the config frame.

When parsing a fixed-integer IEEE C37.118-2011 data stream, ConversionFactor should be 1 in order to assign the raw phasor magnitude to the Measurement.Value field. The MagnitudeMultiplier should be assigned to the Measurement.Multiplier field during input device configuration so that the scaled value can be accessed at runtime via Measurement.AdjustedValue.

This logic should only apply to phasors since PhasorValueBase is the only class that is using ConversionFactor for scaling during parsing/generation.
