Feature request: `clip-retrieval filter` option to return the original image URI instead of the processed image

[nielsrolf]

For building the index, the images are processed to have squared aspect ratio and a fixed size. It would be nice to have an option to return the URI of the original unprocessed image instead of the processed image, for example like this

clip-retrieval filter --query "a cat" --indice_folder "path/to/index" --output image_uris.json
