NewSerialNumber creates a random certificate serial number according to CA/Browser forum spec Section 7.1:

"Effective September 30, 2016, CAs SHALL generate non-sequential Certificate serial numbers greater than
zero (0) containing at least 64 bits of output from a CSPRNG"

func RawCertsFromCertificates

func RawCertsFromCertificates(certs []*x509.Certificate) [][]byte

RawCertsFromCertificates parses ASN.1 DER data from given slice of X.509 Certificates
