Add a field "isResizing" to InteractionState in the onInteractionStateChange callback

[achen187]

I use isZooming and isDragging in onInteractionStateChange because I only make API calls if the user is not in the middle of a zoom or a drag.

I'd love to know whether the user is in the middle of resizing their window as well, so I only make an API call when they're done resizing the window.

This library does not detect if the user is resizing their window. Map resize can be the result of window resize and/or CSS change/animation.

There is also no JavaScript API for "the user in the middle of resizing their window", as resize is a discrete event. You can listen to onResize and debounce any API call from there.
