-generator checks wether a file (path) is already saved in csv-file, if so it skips the file (not sure if it only skips that file or the whole run)
-tqdm-progress bar to generator
-fixed issue of not using the input path to the image folder which is supposed to be loaded but the hard coded path in the code
