docs: Copies bytes from this hash code into {@code dest}.
  
  @param dest the byte array into which the hash code will be written
  @param offset the start offset in the data
  @param maxLength the maximum number of bytes to write
  @return the number of bytes written to {@code dest}
  @throws IndexOutOfBoundsException if there is not enough room in {@code dest}
