pimon minor changes

Elenna noticed that pimon that we run on nuc25 hadn't been consistently saving data. There were large periods of time that didn't have anything recorded. I first verified that it would still write log and npz files, then I redirected them to /ligo/data/pimon/locklosses/ where it will now put all of the npz files. Elenna also asked that the script saves the time series and not the PSDs, so I made that change as well. I'm not sure the file size difference, the PSDs were about 3.6Mb, so we should keep an eye on that and get rid of old ones.

Operators, please verify that pimon is running on nuc25, and restart it if necessary. The normal launch script will start it up.

Apparently, it struggles to save the time series data and will freeze up. I've changed it back to only save the PSDs on lockloss and we'll see if it survives better.
