* [geo] introduce "Auto Zoom" control
On geospatial visualization, checking the "Auto Zoom" control makes it
such that the viewport is fitted to the data upon rendering the chart.
For dashboards with region filters, the map should jump to the right
position.
Eventually we should enhance this to fly and ease to the position in an
animated way.
* Added TODO notes
* DECKGL integration
Adding a new set of geospatial visualizations building on top of the
awesome deck.gl library. https://github.com/uber/deck.gl
While the end goal it to expose all types of layers and let users bind
their data to control most props exposed by the deck.gl API, this
PR focusses on a first set of visualizations and props:
* ScatterLayer
* HexagonLayer
* GridLayer
* ScreenGridLayer
* Addressing comments
* lint
* Linting
* Addressing chri's comments
* [mapbox] fix viewport alterations
Since explorev2 it appears that altering the viewport hasn't been
changing the controls as it used to. This PR addresses it.
* lint
