layer control

[mtennekes]

Working on the next feature: layer control, using mapgl::add_layers_control()

@walkerke :

1. Is it possible to rename a layer? In tmap.mapgl, I use structured names for the layers, e.g. layertmap401polygons_fill, but would like to show other names in the layer control box.
2. Is it possible to group layers? Main use case: for polygons I now use two layers, add_fill_layer and add_line_layer. Ideally, I'd like to have one item for them in the layer control box.

As of right now, neither of those features are implemented. The layers control will always inherit the name of the layer (its id). I also don't have grouping set up, but I can look into both of these!

Awesome, thanks! To be clear: tmap.mapgl is just reactive; in case new features are added to mapgl that are nice for tmap, we'll include them in tmap.mapgl.
