> Currently, if a ByteBuffer is passed into Message(), it treats the buffer as the message's
buffer (including magic byte, meta data, etc) rather than the payload. If you wish to construct
a Message and provide just the payload, you have to use a byte array, which results in an
extra copy if your payload data is already in a byte buffer.
> For optimization, it would be nice to also provide a constructor like:
> this(payload: ByteBuffer, isPayload: Boolean)
> The existing this(buffer: ByteBuffer) constructor could then just be changed to this(buffer,
false).
