Implements NRS with Skew, Stretch, and Squash parameters.
## Parameters
Skew and Stretch are roughly similar to CFG, but decomposed, with `Stretch + Skew = CFG`, roughly.
Skew and Stretch are roughly similar to CFG, but decomposed, with `Stretch + Skew = 2 * CFG`, roughly.
**Skew** changes the 'direction' of generation, which should result in changes to the content and composition of the image.
**Stretch** changes to 'amplification' of generation, which should result in stronger prompt representation.

## Beginner How-To
1. Set Squash to 0.0
2. Set Skew & Stretch each to 1/2 your normal CFG Scale setting
2. Set Skew & Stretch each to your normal CFG Scale setting
3. Test some generation. Results should be 'similar' in quality to CFG
4. Adjust Skew up/down to change content and composition
5. Adjust Stretch up/down to change strength of image aspects and colors
6. Adjust Squash up to remove artifacts and color burn (these will tend to be replaced by additional or extraneous details and elements)
**Tip**: You can experiment with negative values for Skew and Stretch as well to see what the model 'believes' your negative prompt 'means'.
