> SeekerState is the staging site for a Cell while it is being assembled by the BufferedEncodedSeeker.
 When the parent StoreFileScanner calls getCurrentCell() it's guaranteed that the Cell is
fully assembled, and we can directly return the SeekerState as a Cell rather than copying
it into a KeyValue.  A benchmark at the StoreFileScanner level show ~50% faster cells/sec
than when copying to KeyValues (ignoring garbage collection).
