Make the onChange prop not required

[ahuth]

Resolves #99

The component works fine when no onChange handler is provided, because an input is present with the current value. Because of that, submitting a form that this is used in will have the correct param.

I decided to accomplish this by providing a default value of () => {}. That way, existing code can call the callback, and things will still "work", even if no callback was provided.

Hey @hartzis , this solution is a little different than what you proposed in #99. Do you think it's reasonable, or are there downsides to it that I haven't thought of?

@ahuth u rock! This feels like you jumped straight to "step profit 🤑 ".

Honestly, this absolutely should work and glad you remembered defaultProps. it is incredibly powerful.

i think i'd like to pass the creation of the recaptcha a method instead of the props.onChange down the road so it doesn't run into a possible error because it could be referencing an old onChange, but that isn't related to this issue, just made me realize that could be an issue for someone somewhere, lol.

Thank you again for the PR!
