Fly to coordinates in Cesium map

[iannesbitt]

Describe the feature you'd like
DRP team members have requested a way to fly to specific coordinates in the Cesium map. This could exist as a button that reveals a lat, lon text entry field (or two separate fields), which is then used to change the map focus location in a fly to manner similar to that of the behavior after pressing the Home button.

Is your feature request related to a problem? Please describe.
Researchers may be interested in a specific area of the map, which may be easiest to find with a copy/paste of coordinates. This would help researchers and other users zoom to areas of interest quickly.

I think this would be one of the more straight forward features to implement. Here are some pointers:

• The Map Model already has a "zoomTo" method that this widget could call when the coordinates are entered into the entry field
• We could potentially make use of the GeoPoint model to validate the inputted coordinates.
• The widget should be its own independent view that interacts with the Map Model (e.g. see the ToolbarView)
• The MapView should do the work of creating an instance of this widget and inserting it into the map interface.
• We should design this feature with Include interface for searching for a place name or address in Cesium #1796 in mind. For example, the widget we build here could eventually be extended to navigate to not only specific coordinates, but also place names or addresses.

Thanks Robyn! I agree that it would be good to include place names as part of the search functionality. I will take a look at this when I have the opportunity.

Here's a demo of what I have built so far: https://drive.google.com/file/d/1Sukzcv3BjcxH3Pi2fNHLd1g2Oii7LNu7/view?usp=drive_link

I'm working on some unit tests now, but figured I'd share this in case it doesn't match expectations

Looks great @ianguerin! @iannesbitt any comments from the DRP perspective?
