Encode consent data

$cs->setGlobalVendorList($vendorList);

// Set the consent data
$cs->setCmpId(1);
$cs->setCmpVersion(1);
$cs->setConsentScreen(1);
$cs->setConsentLanguage('en');
$cs->setPurposesAllowed([1,2,4]);
$cs->setVendorsAllowed([1,24,245]);

// Encode the data into a web-safe base64 string
