> Similar to ACCUMULO-2445, but presently the encoder only works on complete byte arrays.
This forces an extra copy of the data when it is located in an array that contains other information
(e.g. a composite key).
> It would be nice to be able to provide offset and length arguments to {{Encoder.decode}}
so that users can avoid the additional arraycopy.
> Changing to a ByteBuffer instead of byte array argument would also be acceptable, but
more churn on the API that, unless it's happening globally, I would rather avoid. It would
also incur the penalty for that extra Object, which while minimal alone, could be significant
if decoding every value in a table, for example.
