TransientPropagation: x10 gain when calculating diffusion at pre-step position
After the following commit:
the total gain increases 10-fold.
The problem was spotted using a 75um thick sensor with a gain layer of ~1um. I started observing it while shooting photons with DepositionLaser. The total gain when calculating diffusion at pre-step is ~100. When calculating it post-step is ~10. The tests were done with: multiplication_model = "okuto" multiplication_threshold = 15kV/cm max_multiplication_level = 50
