minimize()
If the prefix contains byte buffers that can be minimized (see
ByteBufferUtil.minimalBufferFor(ByteBuffer)),
this will return a copy of the prefix with minimized values, otherwise it returns itself. |

Please note that this may or may not require an array creation. So 1) you should *not*
modify the returned array and 2) it's more efficient to use ClusteringPrefix.size() and
ClusteringPrefix.get(int) unless you actually need an array.
