Suggestion: Support `X509Certificate` within hash module

[getspooky]

The new X509Certificate(buffer) is an inbuilt constructor of class X509Certificate within hash module which is used to provide a PEM encoded X509 Certificate.

Syntax:

const cert = Deno.readFileSync("public-cert.pem");
new X509Certificate(cert);
// getting subject included in this certificate.
// by using x509.subject function
const value = x509.subject
// display the result
console.log("subject :- " + value)

Output:

subject :- C=IN
ST=Westbengal
L=Kolkata
O=Panco, Inc.
CN=Rohit Prasad
emailAddress=rofofof@gmail.com
