Package Archive: - complete rework of package - split package between compression (stream compression only) and archive (catalogue/dictionary/tape archive type) - rework compression to be stream only working without any temporary file or any like - rework archive like TAR, ZIP... to expose stream instead of writing directly file/path - rework archive like TAR, ZIP... to allow adding file from stream only and allowing to parsing local path to add it into archive - rework detection of compression / archive - rework extractAll function to not using useless local temporary file - adding test can be used as example and perform testing of most of package code - using const custom type for compression and archive allow them to be parsed, marshalled or unmarshalled from text or json and more - apply following change into other module that use it
