Accept geopoints in string format

[scottinet]

Description

Makes Koncorde interpret geopoints coordinates provided as strings instead of numbers.

Filters provided to Koncorde with points in string format are now correctly converted. For instance, the following filter is now considered valid by the standardizer engine:

{
  "geoBoundingBox": {
    "someGeoPoint": {
      "topLeft": { "lat": "40.759507", "lon": "-73.985384" },
      "bottomRight": { "lat": "40.758372", "lon": "-73.984591" }
    }
  }
}

And Koncorde now tries correctly to match documents against registered filters when they contain geopoint in string format, such as:

{
  "someGeoPoint": {"lat": "40.769498", "lon": "-73.984609"}
}
