{LYN-4060} Helios - Fix to load PAK Archive files

* Helios - Archive does not load from PAK files due to IsFileExists() error
* the decompression tag does not need to be ZCRY, so removed it
* the PAK files are on disk, so a "on disk file exists" method is used
* the mapped files m_mapFiles need to track the file path, not just the filename

Tests: Release Launcher with a new level

* re-adding the read only flag check so that ZIP files can be created
