        Returns the provisioning URI for the OTP.  This can then be
        encoded in a QR Code and used to provision an OTP app like
        Google Authenticator.

            https://github.com/google/google-authenticator/wiki/Key-Uri-Format

        :param name: name of the user account
        :param initial_count: starting HMAC counter value, defaults to 0
        :param issuer_name: the name of the OTP issuer; this will be the
            organization title of the OTP entry in Authenticator
