Error map render

In this line, not expect hit._geoloc as Array LatLng.
How do I use this component to render my hits?

Ex Hit:
```{
"type": "store",
"name": "RR Info",
_geoloc: [{
lat: -22.97242,
lng: -43.18958
}]
}```

Read packages/react-instantsearch-dom-maps/src/Provider.js around lines 65 and 105-126, starting with createBoundingBoxFromHits and the render path shown in the stack trace. Verify the expected _geoloc shape against the provided array example and confirm that valid hits render without the Google Maps InvalidValueError.
