/*
 * Node Helper for MMM-OneCallWeather.
 *
 * This helper is responsible for the data pull from OpenWeather.
 * At a minimum the API key, Latitude and Longitude parameters
 * must be provided.  If any of these are missing, the request
 * to OpenWeather will not be executed, and instead an error
 * will be output the the MagicMirror log.
 *
 * Additional, this module supplies two optional parameters:
 *
 *  units - one of "metric", "imperial", or "" (blank)
 *  lang - Any of the languages OpenWeather supports, as listed here: https://openweathermap.org/api/one-call-api#multi
 * Dropped axios and request and used fetch
