When
being a developer, during updateCurrentLocation() method
I want to
send custom meta-data (ie. key value pairs) along with that specific location update
So that
we can tag the meta-data only to single location update and not for all the location update, when we add the same using publishSave() method.

Things to notice

• If the publishSave() method already has meta-data added, this will be overwritten by the meta-data passed in updateCurrentLocation() method and applied only for that specific location update and rest will continue to use the previous configurations passed in publishSave() method.
• The meta-data information should be available below for user location subsciptions.

func didUpdateLocation(_ location: RoamLocation) {
        //Receive user location along with meta-data
    }
func didReceiveUserLocation(_ location: RoamLocationReceived) {
         //Receive other users' location along with meta-data
    }
```</div>
