Add a props onStyleLoad to <Map/>

[zacBkh]

Hello!
First, thanks a lot for the amazing library.

It would be nice to be noticed when style finished loading.
I am talking about style, and not initial map render.

For example, I have a <Map/> of which I toggle style by using react state.
If I switch between multiple style very quickly, I get an error.
I have understood this error is due to the <Marker/> on my map being rendered before the style.

By having something like an onStyleLoad props available on <Map/> I could conditionnally render my <Marker/> depending on if style is loaded or not and avoid this error.

Any other idea ? Feedback ?
Thanks!

After digging, it seems we can use onIdle props for this kind of thing.
