set default value of "event" to "message"

Other language parsers behave consistently and set the value of event to message when the event does not exist.

Thank you! I'm slightly torn on this, since this library is a parser and not a client. By defaulting event to message, we have no way of knowing whether or not an event name was specified. Not sure if there are many cases where that matters - will give it some thought.

In any case, if we do decide to default to message, the event property should no longer be typed as event?: string, but as event: string
