/* Wrapper for using the tls_check_certificate() efun.
*
* If for example the efun returns this raw data:
* ({
* 0,
* ({
* "2.5.4.3",
* "commonName",
* "goodadvice.pages.de"
* }),
* ({
* 0,
* 0,
* 0,
* 0,
* 0,
* 0,
* 0,
* 0,
* 0,
* 0,
* 0,
* 0,
* "2.5.29.17",
* "X509v3 Subject Alternative Name",
* ({
* "dNSName",
* "dNSName",
* "goodadvice.pages.de",
* "1.3.6.1.5.5.7.8.5",
* "1.3.6.1.5.5.7.8.5",
* "goodadvice.pages.de"
* })
* })
* })
*
* the wrapper will transform it into:
* ([
* 0: 0
* "2.5.29.17:dNSName": "goodadvice.pages.de",
* "2.5.4.3": "goodadvice.pages.de",
* "2.5.29.17:1.3.6.1.5.5.7.8.5": "goodadvice.pages.de",
