/**
 * Decodes the specified region of the buffer into an unadjusted frame length.  The default implementation is
 * capable of decoding the specified region into an unsigned 8/16/24/32/64 bit integer.  Override this method to
 * decode the length field encoded differently.  Note that this method must not modify the state of the specified
 * buffer (e.g. {@code readerIndex}, {@code writerIndex}, and the content of the buffer.)
 *
 * @throws DecoderException
 *         if failed to decode the specified region
