PdfProcessing: InvalidCastException is thrown when importing URI Action with URI property of type PdfHexString
By specification, the URI property of URI Actions is encoded in 7-bit ASCII string. For this reason, our current implementation relies on that the property will be of type PdfLiteralString. However, in cases such as password-encrypted documents, the property may be encoded with PdfHexString which leads to InvalidCastException: 'Unable to cast object of type Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Types.PdfHexString' to type 'Telerik.Windows.Documents.Fixed.FormatProviders.Pdf.Model.Types.PdfLiteralString'.', on document import.
