Fix Mapbox attribution on lower left when MB map enabled

[danrademacher]

We're properly switching from "© Carto" to "© Mapbox" in the text credit in lower right of the map, but the Carto logo is persisting on lower left:

Looks like there's info here on how to pull in their wordmark:

will need to switch back and forth as basemap changes

@danrademacher the Carto logo is required to be displayed for their non-profit grants program.

Hmm, and when we are using a Mapbox map, they want their logo. We don't want to have two logos showing. I will check with Tyler at Carto to clarify requirements around the logo on the app.

The mapbox attribution displays in the lower right when you have the Mapbox basemap enabled, which I think is sufficient.

Not according to their documentation:

If you are using Mapbox maps with another open source library, like Leaflet or OpenLayers, the Mapbox wordmark and attribution are still required.

Although I'm noticing when the app first loads the Positron tiles display by default and the Mapbox attribution is incorrectly displayed. After a new basemap layer is toggled the attribution is correct.

@danrademacher it seems less concerning as they aren't giving us a grant IMO.

OK, everyone requires logos (strike down one advantage of not using Google...). Tyler from Carto confirmed that any view using Carto tech (most of them) needs Carto logo, regardless of basemap. Mapbox requires their logo when their basemap in use.

Solution, move scale bar up, Carto logo to far left:

And with Mapbox logo (approximate):

Tried to space it as tightly as possible:
