return adjust_saturation(image, saturation_factor)
Adjust the saturation of an RGB image by a random factor.

  Equivalent to `adjust_saturation()` but uses a `saturation_factor` randomly
  picked in the interval `[lower, upper]`.

  Args:
    image: RGB image or images. Size of the last dimension must be 3.
    lower: float.  Lower bound for the random saturation factor.
    upper: float.  Upper bound for the random saturation factor.
    seed: An operation-specific seed. It will be used in conjunction
      with the graph-level seed to determine the real seeds that will be
      used in this operation. Please see the documentation of
      set_random_seed for its interaction with the graph-level random seed.

  Returns:
    Adjusted image(s), same shape and DType as `image`.

  Raises:
    ValueError: if `upper <= lower` or if `lower < 0`.
