Update noise simulation for ProtoDUNE single phase
It would be great if we could update the noise simulation for ProtoDUNE single phase.

The goal is to have noise level and frequency spectrum similar to that seen in the data.
The simulation uses ExponentionalNoiseSevice which has exponentially falling noise with a flat floor at high frequency. The data also flattens out at low frequency below 200 kHz.
The service has parameters for a low frequency rollover but when I change one of those, I see a sharp drop below the specified frequency.
I have modified the code so that a negative value for the rollover frequency give a flat spectrum below the magnitude of that value. I will now try to tune the params so sim matches data.
