be2cf70da8 Fix serialize/deserialize of denominator of Average functions 
Use writeBinary/readBinary to serialize/deserialize the denominator of Average functions.

Previously it would be transmitted as an unsigned int, which means its value would get corrupted when doing an avgWeighted over a floating point number.

Note: this commit is not backwards compatible!
