mesteps should be scaled. Refer to Table 2 of the Common Diffusion Noise Schedules and
Sample Steps are Flawed for more information.   timestep_scaling (float, defaults to 10.0) —
The factor the timesteps will be multiplied by when calculating the consistency model boundary conditions
c_skip and c_out. Increasing this will decrease the approximation error (although the approximation
error at the default of 10.0 is already pretty small).   resca
