Abstraction for Requests Containing Multiple Tile Layers

[murphy214]

Hello!

I wish I would have found this project a few days ago, its pretty awesome! However I had a look through the code and some of the pull requests as I couldn't get more than one layer to load into the same vtLayer being requested from a byte array with a few layers, and that may be by design, but practically speaking if you have 10 layers in 1 request, you'd like to avoid sending and loading that vt request 10 times.

However I could not find any abstraction or evidence of any layer names in raw form being used in any object through out the code or object in console, I see that this is built on top of leaflet's grid layer, is it possible to have more than one layer in an mvt layer? (I think its being loaded in completely just not added to the vtLayer) I could just be not paying attention and an example exists somewhere.

If this hasn't been an issue yet I apologize but do you guys have any plans for abstracting this out either using another structure or vtLayer? I'm not super good at js, but I do know quite a bit about vector tiles and could probably help. I know this will undoubtedly cause a lot more complexity but I think its worthwhile. Let me know if I can help with anything!

Thanks in advance,
Bennett
