Returns a BidiFlow that implements a simple framing protocol. This is a convenience wrapper over LengthField(Int32, Int32, Int32, ByteOrder) and simply attaches a length field header of four bytes (using big endian encoding) to outgoing messages, and decodes such messages in the inbound direction. The decoded messages do not contain the header. This BidiFlow is useful if a simple message framing protocol is needed (for example when TCP is used to send individual messages) but no compatibility with existing protocols is necessary. The encoded frames have the layout {{{ [4 bytes length field, Big Endian][User Payload] }}} The length field encodes the length of the user payload excluding the header itself.
