Motivation: We accidentally removed the 'NIOFileSystem' module from the '_NIOFileSystem' product in the last release. Modifications: - Rename 'NIOFileSystem' and 'NIOFileSystemFoundationCompat' to 'NIOFS' and 'NIOFSFoundationCompat' - Add back 'NIOFileSystem' which re-exports '_NIOFileSystem' (there was no publicly available 'NIOFileSystemFoundationCompat' module to remove, only '_NIOFileSystemFoundationCompat'). Result: Fewer breaks
