Added a "gamma" slider to pyramid NR. Noise reduction is carried out with L channel mapped to that gamma. Default value is 2.0; lower values increase shadow smoothing, higher values smooth highlights more. Unfortunately adjusting this slider interacts with the other two, so all three have to be iteratively adjusted to achieve a desired result.
