        public Signature​(byte[] certificateRawData,
                         String password,
                         Instant signatureDate,
                         byte[] signatureImage,
                         String signingContact,

                         String signingReason)
        Initializes a new instance of the Signature class.
        Parameters:
        certificateRawData - the certificate as a binary data (byte array).
        password - the certificate's password.
        signatureDate - the date and time of the digital signature. If left null, the signature will be timestamped at the millisecond that the PdfDocument is saved to Disk or Stream.
        signatureImage - a visual image for the sign, often a PNG of a human signature or company stamp (optional).

        This appends a visual signature in addition to cryptographic signing.
