Inventory API wrong datatypes on Location

```
public class Location
{
    public Address Address { get; set; }

    public GeoCoordinates GeoCoordinates { get; set; }

    public string LocationId { get; set; }
}

public class GeoCoordinates
{
    public string Latitude { get; set; }
    public string Longitude { get; set; }
} 
```

Latitude and Longitude should be a decimal. Please check it, it's thrown an exception.
