NewPFD/NewPFOR based on Simple16 by Yan et al.

using Simple16 as the secondary coder. It encodes integers in blocks of 128 integers. For arrays containing an arbitrary number of integers, you should use it in conjunction with another CODEC:

IntegerCODEC ic = new Composition(new PDFS16(), new VariableByte()).

Note that this does not use differential coding: if you are working on sorted lists, you must compute the deltas separately. For multi-threaded applications, each thread should use its own NewPFDS16 object. @author Daniel Lemire
