bpo-43650: Fix MemoryError on zip.read in shutil._unpack_zipfile for large files (GH-25058) (GH-26190)
`shutil.unpack_archive()` tries to read the whole file into memory, making no use of any kind of smaller buffer. Process crashes for really large files: I.e. archive: ~1.7G, unpacked: ~10G. Before the crash it can easily take away all available RAM on smaller systems. Had to pull the code form `zipfile.Zipfile.extractall()` to fix this
