> Made acceptableOverheadRatio configurable 
> Added bulk get to AbstractAppendingLongBuffer classes, for faster retrieval.
> Introduced a new variant, AppendingPackedLongBuffer which solely relies on PackedInts
as a back-end. This new class is useful where people have non-negative numbers with a fairly
uniform distribution over a fixed (limited) range. Ex. facets ordinals.
> To distinguish it from AppendingPackedLongBuffer, delta based AppendingLongBuffer was
renamed to AppendingDeltaPackedLongBuffer
> Fixed an Issue with NullReader where it didn't respect it's valueCount in bulk gets.
