Create scope like program -- CLI version

Create a command line program (using import cmd) where one can set:

module
channel (perhaps the channel command should take 2 argument, <channel number> and <name>, so that the <name> can be used when we save data)
Fast filter: L, G, threshold
Energy filter: L, G, tau, peaksample
CFD: w, L, G, D, CFD_treshold
CFD on/off
Coincidence on/off

The program should also have an option to

load a setting file
list all above settings for this channel
start an MCA run (N seconds)
take list mode data (N seconds)
Or perhaps always do both or perhaps do list mode only once and skip it when doing repeat measurements.
option to save data and plots (plots should be annotated with metadata from above + date+ git version, etc.), plots should perhaps be separate windows (or a plt.subpots(2,1)) for MCA and listmode.
clear plots
remember plots and plot in gray for easy comparison (e.g. whenever we save data, we should also copy the data into a data structure, say old_data = […]), so that we then can do issue commands like “plot add 3” or “plot remove 3”, where 3 would be the 3rd saved datafile of this run

Behavior:

The program then takes either MCA data and displays it in matplotlib window. taking more data should always add it to the spectra.
Taking list mode data should take data for 5s, select several traces by amplitudes, so that we get a good distribution, e.g. 2% of max, 10% of max, 20% of max, etc. The traces should be plotted. Taking more data doesn’t really make sense, unless there are not enough traces to get a good sample.
Changing any setting should directly call the pixie16 settings structure and clear the plots

Implementation:
