DALL-E generated image downloader

This script allows the user to download all four generated samples by pressing "d" on openai's DALL·E image generation software

- If you generated variants of an image, it will download only the variants
- The files will be saved under the same name ("prompt.png ± (n° of the image)"
- The script loads 2.5 seconds after the page is reached because openai restricts location.onloadend
- If you press "d" while writing in the input prompt nothing will happen
