This is the inverse of the independent bits engine, it down-samples the resolution of the underlying engine, eg it calls the underlying 256 bit engine once every 4 rounds to generate 64 bit random numbers. Maybe we can isolate this functionality into a separate engine adaptor? Right now I have this implemented as an array view on an array with elements of different byte size.
