This is a fairly simple JSON format: A single array, containing objects, with the Annotation fields as key:value pairs. When reading a file, we let invalid or missing keys fall back to the default values. This is mostly intended to set a pattern so that if we add new fields in the future, we won't fail to load old annotations files. If loading the file fails though, we keep the previously loaded set of annotations.
