What types of image mutations are available in the `augmentations` parameter?

Within each `augmentations` block, you can specify a `mutations` list. Available mutations include geometric transformations like `horizontalFlip`, `verticalFlip`, `rotateLeft`, and `rotateRight`, as well as appearance modifications such as `colorJittering`, `colorShifting`, `darken`, `lighten`, `sharpen`, and `invertPixels`.
