is geojson fetchable from mb layers?
Canvas BBox: Four geographical coordinates, represented as arrays of longitude and latitude numbers, which define the corners of the image. The coordinates start at the top left corner of the image and proceed in clockwise order. They do not have to represent a rectangle.
    coordinates: [
        [west, north],
        [east, north],
        [east, south],
        [west, south],
    ],

todo
- solve async problem w/ node stdin/out
  - update addPopulation to use stdin/out, po
- states: finer detail
  - usstates.geojson 87K, us_040_00_20m.json 1.4MB, 5m 2.4MB?
- counties: featureState seems backwards!
- find source for all data/ files, put in npm run scripts

Issues:


- Key problem is that mapbox gl js doesn't use js where you'd like (expressions)

- Filtering on feature ID:
    string ("05") converted to number causing multiple hits in string using "in" expr. Soln is to use an array I suspect
// REMIND: fix, id is numeric!
// filter:
//     states.length === 0
//         ? ['to-boolean', true]
//         : ['in', ['id'], fips],
// : ['==', ['id'], states],
