[WiP] Integrate Kepler.gl as a new visualization type
Kepler.gl is an amazing geospatial React application. It offers a very well designed user interface to compose geo layers and slice and dice geospatial data. As it turns out, Kepler is designed to be embedded as part of React apps. It took me only a few hours to get to a working prototype. Next steps: * allow to save the state, without the data * restore the state, and merge with the new data * tweak styles, make a light style that looks decent within Superste, Kepler uses stylable components, so that should be somewhat straigthforward (cherry picked from commit 43ed9a6) (cherry picked from commit 595832a) (cherry picked from commit 1fa1d05) (cherry picked from commit 791776e) (cherry picked from commit 568afd4)
