Hypercore.createProtocolStream() has slightly different behaviour when you pass it a Protomux instance instead of a raw duplex stream or a noise stream: in the latter cases it returns the raw outer stream (e.g. the noiseStream.rawStream), but when you pass a protomux instance it returns the noise stream. Not something that comes up much, but it's confusing.
