Improve user experience if user attempts to click map outside of Alaska

Currently, if the user clicks a point outside of Alaska, it will:

Zoom in on the map
Not clear the air quality table, if a location within Alaska was clicked previously

Ideally, it'd be better to not zoom in, and clear the air quality table or replace it with a "No air quality data for this location" message. And maybe even replace the cursor with a "no entry" sign similar to our Fish & Fire app. But this all requires a lot more work, so probably something for future consideration.
