See if we can support an additional map zoom level

[barbeau]

Summary:

We're looking at using the USF Maps App on TVs in display lobbies. As part of these installations, we'd like to add another zoom level to allow us to zoom in a bit further.

We've had a lot of transitions with the map tiles - I want to say we capped this for a reason with Mapbox tiles as well, although maybe we can reexamine this with hosting our own map tiles (#398).

From Donny at CUTR:

zoom level 19 would be pretty much perfect. It looks like maps.usf.edu is capped at 18. Here’s what 19 looks like on OSM/GMaps:

Steps to reproduce:

Zoom in to CUTR on the map

Expected behavior:

We'd like to zoom in one more level

Observed behavior:

Looks like we're currently capped at zoom 18

From @liquidsunshine, regarding priority of some of these related issues for using the app to show information in the CUTR lobby on a TV display:

Here’s how I would prioritize them, based on CUTR’s needs:

1. Route polylines don't show when visiting direct link to route layers #401 (a bug)
2. Make map zoom and center configurable via URL parameters #403 (allows us to automatically center on CUTR)
3. Add URL parameter to turn off "Don't use while driving" #404 (allows us to automatically bypass popup)
4. See if we can support an additional map zoom level #405 (offers a better view of CUTR)
5. Make client-side refresh rate configurable via URL parameter #402 (possibly improves refresh performance)
