* Change low to high transition and global zoom
- change the low to high transition from 7 to 5. This can not go any lower as high tiles on AWS only go to zoom level 5
- reduce the zoom level globally on all census tracts
* Remove geolocation from feature flag
- geolocation is now available to all
* Add python notebook that sorts all tracts by area
- add a column of the required zoom level for the tract to be fully contained in the viewport
* Place geolocation back to behind a feature flag
* Differentiate zoom levels b/w shortcuts and tracts
