In scenarios where byte array JSON messages are forwarded (e.g., from MQ), the previous approach required unmarshalling into an object before encoding for SSE.

The updated logic allows []byte to be passed directly, simplifying message forwarding and reducing unnecessary conversions.

	// before
	byteData := messageFromMQ()
	data := make(map[string]any)
	json.Unmarshal(byteData, &data)
	sse.Encode(new(bytes.Buffer), sse.Event{
		Data: data,
	})

	// after
	byteData := messageFromMQ()
	sse.Encode(new(bytes.Buffer), sse.Event{
		Data: byteData,
	})
