CLI: action combine: --ignorefileextension to ignore PDF/A input file errors dosen't work

[joergenp]

when combining a pdf (created as PDF/A-1b with Libre Office) with a xml the CLI throws
ERROR ROOT - File is not a valid PDF/A-1 input file
independent of option --ignorefileextension.

By looking at the source I can see that .load(pdfName) ist called before .ignorePDFAErrors() (code line 715-728):

				ze = new ZUGFeRDExporterFromPDFA().load(pdfName);

					ze.setProducer("Mustang-cli")
					.setZUGFeRDVersion(zfIntVersion)
					.setCreator(System.getProperty("user.name")).setProfile(zfConformanceLevelProfile);
				if (ignoreInputErrors) {
					((ZUGFeRDExporterFromA1) ze).ignorePDFAErrors();
				}
			}
			for (FileAttachment attachment : attachments) {
				((ZUGFeRDExporterFromA3) ze).attachFile(attachment.getFilename(), attachment.getData(), attachment.getMimetype(), attachment.getRelation());
			}

//			ze = ze.load(pdfName);

Seems this was introduced on #341

I added a test for the functionality itself in [d22a8a0] , unfortunately I cant test end-to-end yet due to a Exception in thread "main" java.lang.NoClassDefFoundError: jakarta/activation/DataSource... I hope I can fix that soon
