comfyanonymous dcec1047e6 Invert the start and end percentages in the code. 
This doesn't affect how percentages behave in the frontend but breaks
things if you relied on them in the backend.

percent_to_sigma goes from 0 to 1.0 instead of 1.0 to 0 for less confusion.

Make percent 0 return an extremely large sigma and percent 1.0 return a
zero one to fix imprecision.

comfyanonymous 844dbf97a7 Add: advanced->model->ModelSamplingDiscrete node. 
This allows changing the sampling parameters of the model (eps or vpred)
or set the model to use zsnr.
