Make urls for tabs bookmarkable

[cypressf]

Problem

If you refresh the page, it loses your spot (if you were on the water tab, you no longer are).

Solution

Now that react-router-dom works with the apache config, I should be able to change the url based on the tab you're on.

e.g.

est.mit.edu/water

https://github.com/cypressf/climate-risk-map/commit/a723343ff601263f78abfffacc9705e93d73281b enables linking to a data tab. Next I'm going to implement linking to a specific map within a tab, but I'll make a separate git issue for that because it's significantly more complex
