fix: update Map event listeners on prop changes

[chwallen]

When updating the event listener props, the MapGL component does not propagate these changes to the underlying Mapbox instance. This makes it impossible to use state inside, for example, the onClick event handler as it will be bound to the first render. It also makes it impossible to remove event handlers dynamically.

This PR updates any event listeners that has changed in a similar way to how componentDidMount applies the initial listeners.

Fixes #324
