Bugfix for Directional Pyramid Denoising. Adding a Directional Pyramid Equalizer tool. This one serves the same function as the existing Wavelet Equalizer, but has much less artifacting; though it is a little slower to execute and has not yet been adapted for OpenMP implementation. There are also fewer levels on which the tool operates, though of course if there was a demand that could be altered. The controls are similar, though have been given separate luma and chroma controls. Each slider adjusts the factor by which a given detail band is amplified; factors larger than one increase contrast, while values smaller than one decrease contrast. The luma control alters contrast on various scales, each successive one twice as large as the previous one. The chroma control is similar, but does less since there is typically less chroma contrast on fine scales. One might use this to restore some of the color contrast lost in NR, or to remove color fringing by making the fine scale enhancement factor much less than one.

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.

Added a threshold slider to the impulse denoise tool. At large values it can lead to a bit of cratering, but otherwise it allows some flexibility that is useful as a precursor to the pyramid denoise filter. Small values on the slider are less impulse NR, larger values yield more NR.

Added a threshold slider to the impulse NR tool. Large values can cause cratering, but otherwise this should be a good precursor to pyramid denoising.
