PDFBOX-4307: check object type before casting to COSDictionary in PDDocumentCatalog.getDocumentOutline

> In PDDocumentOutline.getDocumentOutline() the 'outline' is read as dictionary object and directly cast to COSDictionary. Normally this is ok as it should be a dictionary. However in a bad PDF as I have it in my collection (unfortunately I'm not allowed to disclose it) the object is an array (COSArray) which leads to the ClassCastException.
> Since the outline is an optional information the best we can do here is to ignore the 'outline' data if its not a COSDIctionary and return 'null'.
