‘chloropleth’ API endpoint

[loarie]

endpoint that takes taxon_id and place_id array (as well as other obs search params, e.g.
api.inaturalist.org/v1/observations/choropleth?places=14,12&taxon_id=2041&verifiable=true…
and returns observation counts by places in the array. All I need at the moment is place_id, obs_count, e.g.:

{
  "total_results": 357,
  "page": 1,
  "per_page": 357,
  "results": {
    "places": {
      "13": 7,
      "15": 30,
      "16": 41,
      "18": 52,
      "31": 97,
      "54": 90,
      ...
    }
  }
}

but it might be wise to include the place object in the response if we wanted to anticipate other uses, e.g.:

{
  "total_results": 494,
  "page": 1,
  "per_page": 494,
  "results": [
    {
      "place": {
           name: "California",
           id: 14,
           ...
      },
      "observations_count": 10,
    },
    ...
  ]
}

I would find this useful as well!
