Serialize a PFX to an Encoded String

Demonstrates Pfx.ToEncodedString, which serializes the current PFX contents and returns the PKCS#12 bytes encoded as text using a named encoding.

Background. Common encodings are base64 and hex. This is convenient when the PKCS#12 data must be stored or transmitted as printable text.
