Incorporate more Yukon area types

[cstephen]

Closes #630.

This PR, along with its corresponding API PR (https://github.com/ua-snap/data-api/pull/407), incorporates the following Yukon areas into NCR:

• Yukon Fire Districts
• Yukon Game Management Subzones
• Yukon Watersheds

To test:

• export SNAP_API_URL=http://localhost:5000
• Run both the API and NCR from their respective more_yukon_areas branches.
• Clear your local storage for http://localhost:3000 to make sure your browser fetches the new place IDs/names/etc.
• Try clicking a few areas within the Yukon territory on NCR's location search map. Verify that each of the new Yukon area types are represented in the search results. Similar to Alaska's Fire Management Zones, Yukon Fire District polygons are not drawn on the map because they can be quite large. But all three of the new Yukon area types should show up in the bulleted list of search results if they intersect the point to clicked.
• Load some reports for the new Yukon area types and verify that they load as expected & have some data.

Setting this PR as draft mode for now since it would be too ambitious to merge it (+ the corresponding API PR) before our upcoming launch. I think the PR is good to go otherwise, so we'll want to set it back to non-draft mode sometime after the upcoming launch.
