Possibly outdated `mapbox-gl` peer dependency

[Ickerday]

To quote package.json:

"peerDependencies": {
  "mapbox-gl": ">=0.29.0 <2.0.0"
},

Is there a reason for this peerDep to be capped at 2.0.0?
I'm happy to submit a PR for this but I'd like to confirm if this is intentional before I do so.

Hey, I ran into the same problem. I "force" installed the library and it seems to work. But it would be great if this can be resolved.

I noticed there is no icon on the button.
