Expand compatible format pool in the Nachet-interactive

[hanzi4389604]

From the README.md file, .tiff format will be used for the Nachet-interactive. I think we might be good to include JPEG, PNG, and other common format.

The reason I prompt up this question is that: there is a small bug related to image format in the Nachet-interactive https://nachet.ninebasetwo.xyz/. When upload a .tiff image, the interface does not show image but interestingly can do image classification. The Nachet-interactive seems only compatible with .jepg and .png image.

I reported this issue in ai-cfia/nachet-frontend#89
