Satamp swap OSEM noise first looks

I ran my damp_regression_compare script (85369) on the suspensions that we swapped the satellite amplifiers for today, BS, PRM, PR3, SRM, and SR3. The results show a decrease in the OSEM noise of at least 2x!

Part of what the script does is save the channel data as a .mat file so it's quicker to run next time, so I'll post that as well as the results.

Since a few of the before times I picked for some of the suspensions were during times where they had ISC control on, I've rerun them with a better starting time where there was no ISC control
