code: public static SaneWord fromBytes(byte[] byteValue, int offset) {
      Preconditions.checkArgument(offset >= 0, "offset must be positive or zero");
      Preconditions.checkArgument(offset + SIZE_IN_BYTES <= byteValue.length);
      return new SaneWord(Arrays.copyOfRange(byteValue, offset, offset + SIZE_IN_BYTES));
    }
docs: Creates a new {@link SaneWord} from a copy of the given bytes within the array.
  {@code offset + SIZE_IN_BYTES} must be a valid index (i.e. there must be enough bytes in the
  array at the given offset), otherwise a runtime exception is thrown.
