-- Added progress bar according to @ArmandBernard 's suggestion.
-- Cache folders are now created under `'{}\\video2x'.format(tempfile.gettempdir())` by default, and the default key for cache folder location in configuration file has been changed to `video2x_cache_folder`. This makes it easier to manage cache folders.
-- Cache folders are now more likely to be deleted successfully even if the program crashes. This is made possible with more try-catch blocks.
