fix: 🐛 improve image handling in read_image_as_pil for CHW format

[onuralpszr]

# check if image is in CHW format (Channels, Height, Width)
        # heuristic: 3 dimensions, first dim (channels) < 5, last dim (width) > 4
        if image.ndim == 3 and image.shape[0] < 5:  # image in CHW
            if image.shape[2] > 4:
                # convert CHW to HWC (Height, Width, Channels)
                image = np.transpose(image, (1, 2, 0))
        image_pil = Image.fromarray(image)
