Add event to toggle handlers

[Nicktho]

Hi there, great library!

I have a use case for handling the click event of the hamburger component. I've gone ahead and suggested a way to incorporate it into the api, as a second argument to toggle and onToggled, let me know what you think!

Thanks for the PR! I was actually planning on removing onToggle in 3.0, in favor of:

useEffect(() => {}, [toggled])

Besided that, a few questions about this PR:

• Can you explain a little bit about the use case?
• How would you use/read the second variable (the click event) in this typical setup?

const [toggled, toggle] = useState(false)

<Hamburger toggled={toggled} toggle={toggle} />

Just wanted to drop by saying that I need the click event to stop propagation. I know asking for something without contributing is not really the nicest thing to do, but this may help you prioritise new features.
