I would like to start testing Roseate with these more professional types of image formats so I would like to add support for the tiff image format via the image-rs backend in roseate-core.

Image-rs has a decoder for it so it shouldn't be too hard to add hence why this is tagged as a good first issue.

Here's where the image-rs backend can be found: https://github.com/cloudy-org/roseate/blob/refactor!/roseate-core/core/src/backends/image_rs/mod.rs
