> When decoding values from a KeyValueSchema data object, we should check that the length specified (either by its type of fixed length or by the length flag) does not exceed maxOffset.
> Meanwhile, maxOffset should not be the total length of the ImmutableBytesWritable object, but instead should be the total length minus the length of the tailing valueSetBit.
