This method is the core generation algorithm. It is used by all the
public generation methods for the various primitive types BitsStreamGenerator.nextBoolean(), BitsStreamGenerator.nextBytes(byte[]), BitsStreamGenerator.nextDouble(),
BitsStreamGenerator.nextFloat(), BitsStreamGenerator.nextGaussian(), BitsStreamGenerator.nextInt(),
BitsStreamGenerator.next(int) and BitsStreamGenerator.nextLong().
