Setting consentLanguage without forcing another fetch

Version 1.5.11

Module Core

Reason Calling the changeLanguage method on the GVL class will trigger a new request, resulting in some 404 errors. There are a couple of open tickets related to this issue:

• Cant set consentLanguage with custom GVL #211 https://github.com/InteractiveAdvertisingBureau/iabtcf-es/issues/211
• GVL object is being constructed with the gvl json, and setting consentLanguage forces another fetch #405 https://github.com/InteractiveAdvertisingBureau/iabtcf-es/issues/405

What we propose is to add a boolean value to SKIP the fetch request, like:

if (!skipFetchCall) { await this.fetchJson(url);
}
