/**
 * Aelia Currency Switcher - Fetch the geolocation country from Cloudways.
 * The code in this example will take the country from the header set by Cloudways 
 * (if present) and skip the internal geolocation logic used by the Aelia plugins, such
 * as Aelia Currency Switcher, Aelia Prices by Country and Aelia Tax Display by Country.
 * 
 * For more information about the geolocation feature offered by Cloudways, please
 * refer to their documentation: https://support.cloudways.com/use-geoip-with-your-application/
 * 
 * IMPORTANT
 * Plugins like the Aelia Tax Display by Country also handle the county/province/state, 
 * which Cloudways doesn't return. In that case, the plugin will still use its internal 
 * logic to fetch that information.
