Add geocoding API for setting multiple languages

[cammace]

Currently we only allow the setting of one Language for the geocoder. The Geocoding API will allow multiple Locales to be passed in. mapbox/MapboxGeocoder.swift#104

Note this needs to be exposed in both MapboxGeocoder and Geocoding widget.

@cammace Is this actually fixed now. I'm using the mapbox-sdk-services:4.1.0-SNAPSHOT for my Android project.

MapboxGeocoding.builder()
.accessToken("")
.query(Point.fromLngLat(-123.1207, 49.2827))
.languages(new Locale("ru"), new Locale("zh-CN"))
.geocodingTypes(GeocodingCriteria.TYPE_PLACE)
.mode(GeocodingCriteria.MODE_PLACES)
.build();
Still returning only one language. Not returing all requested language.
Could you please confirm this.

Thank you @cbadhrinath.

@osana could you look into this? I don't think we have a test covering this usecase (multiple languages in the request and multiple languages in the response).

@zugaldia I will check this out

Thank you for reporting this.
I confirm that there is a problem in supporting
https://api.mapbox.com/geocoding/v5/mapbox.places/-77.0366,38.8971.json?access_token=pk...&language=en_us,ru,es

We correctly do the request for multiple languages but the response object is not parsed correctly.

Here is one of the CarmenFeatures returned from the above request
