rawjson-as-bytes returns a json.RawMessage type, should be []byte

We had a discussion about this recently with the CloudEvent type - we didn't want to expose json.RawMessage since it'd potentially cause issues in the future when a new JSON package comes around.

I think it's as simple as using a []byte() around the returned value since json.RawMessage == []byte.

func (e *Event) UnmarshalJSON(data []byte) error {
	var rawMsg map[string]json.RawMessage
	if err := json.Unmarshal(data, &rawMsg); err != nil {
		return fmt.Errorf("unmarshalling type %T: %v", e, err)
	}
	for key, val := range rawMsg {
		var err error
		switch key {
		case "data":
			e.Data = val    // <--- I believe this is incorrect - we don't want to surface json.RawMessage as a type. 
			delete(rawMsg, key)

(offline discussion, but want to mention that the Data field is typed any).

Oops, okay - here's the deal:

If you choose raw-json-as-bytes Data is also changed to be of type []byte, making the assignment I outlined above safe. So we can close this one and I lose my dreams of filing a valid autorest bug.
