Fix multi-part RAR extraction: use VolumedArchiveInStream for .partN.rar

The JVM extractor used RandomAccessFileInStream for multi-part RAR archives,
which only provides a single file stream. 7z-JBinding requires
VolumedArchiveInStream to access additional volume parts via callback.

Added RAR_MULTIPART_RE and RAR_OLDSPLIT_RE patterns to detect multi-volume
RAR archives and route them through VolumedArchiveInStream, fixing
"Archive file can't be opened with any of the registered codecs" errors.
