Image display with sidecar JSON

Some file formats need to know in advance some informations about the image. For example, the PLAIN RAW format is just a simple dump of a buffer into a file, thus it needs to know how to interpret the data. In this case, user need to have an image sidecar JSON located next to the image file as the same name and path path_to_image.json

{
    "fileInfo": {
        "format": "plain",
        "height": 3072,
        "width": 4080
        "pixelPrecision": 16,
        "pixelType": "bayer_gbrg",
    }
}

After image reading, the information in JSON sidecar will be shown in tab Widegt of ImageMetadata
