Aggregation.ExtendedStats is not working

[thrane]

We are using the aggregation with extended stats, and with the newst version of elasticsearch we get a serialization error from elasticsearch.net when we query with this aggregation.
our code looks like this:
Aggregations(a => a
.ExtendedStats("bar", f => f.Field(field => field.Bar))
.Stats("foo", f => f.Field(field => field.Foo))
.Sum("sum", f => f.Field(field => field.FooBar)));
The error we are getting is this:

Unexpected token when deserializing object: StartObject. Path 'aggregations.mileage.std_deviation_bounds', line 1, position 453.

Thanks for reporting @thrane, just opened #1282 which fixes this.
