udf format support

[cppdev-123]

I'm trying to extract a windows image and then compress it again to iso file

the problem is that the the extractor detects that the compression format is cab and extracts some garbage after consuming too much of the disk io speed

so I change the format to Iso but now it extracts a one file named README.txt which contains : ""This disc contains a "UDF" file system and requires an operating system that supports the ISO-13346 "UDF" file system specification.""

I opened the iso file with 7-zip and found that the format is udf and it is able to extract it , thus I assumed that this library lacks support for udf files

Seems similar issue to https://sourceforge.net/p/sevenzip/discussion/45797/thread/43e9ad6d/. Since we use com port for the operations I wonder if we don't have the same limitations. https://sourceforge.net/p/sevenzip/discussion/45797/thread/21f213e2/ is a more recent discussion. It seems UDF 2.5 might be supported but it's not guaranteed. If anyone knows the steps to add udf support, make a pull request and I'll happily merge it.
