Adds EXR format to store depth images in float32
MEMBER
Hi ! I'mn wondering if this shouldn't this be an `Image()` type and decoded as a `PIL.Image` ?

This would make it easier to integrate with the rest of the HF ecosystem, and you could still get a numpy array using `ds = ds.with_format("numpy")` which sets all the images to be formatted as numpy arrays

@lhoestq do you mean to add the decoder, and exr extension to the image format? Yes, that probably would be better

This PR adds the EXR feature to store depth images (or can be normals, etc) in float32.
It relies on [openexr_numpy](https://github.com/martinResearch/openexr_numpy/tree/main) to manipulate EXR images.
