Description
The class PDComplexFileSpecification needs to be improved as follows:
- analog to "get/setFileXXX" we should add the missing get/setEmbeddedFileUnicode
- we should rename getUnicodeFile to getFileUnicode to be inline with the other getters and add a setter for that value as well
- according to the spec, the Dos, Unix and Mac mutations shouldn't be used anymore, therefore we should rearrange the order in "getFilename"
