Please Add 'distanceField' in mongodb geoNear query

[Siltaz]

I'm trying to make a geoNear query:

            '$geometry' => [
                'type' => 'Point',
                'coordinates' => [
                    $longitude,
                    $latitude
                ],
            ],
            '$maxDistance' => 2000,
            'distanceField' => 'distance'

and getting an error "invalid argument in geo near query: distanceField"

But MongoDB supports 'distanceField' option. Reference https://docs.mongodb.com/manual/reference/operator/aggregation/geoNear

Please add 'distanceField' in geo near query, this will make this library better !!
And thanks for this amazing library 👍

$rs = $this->raw(function ($collection){
return $collection->aggregate([
[
'$geoNear' => [
'key' => "coordinates",
'near' => ['type' => "Point", 'coordinates' => [ 116.414326, 39.922964 ] ],
'maxDistance' => 1000,
'distanceField' => "distance",
'spherical' => true
]
]
]);
});
return $rs;

Thanks @qingdi ! That works! I'll make a pull request on the readme with that instruction!
