Remove energy spectra for TAC cut by default

[ckierans]

There is a tab in the Nuclearizer GUI for an energy spectra intended to be used before and after the TAC cut; however, the standard operation is to run the TACCalibration module before the EnergyCalibration module, so these spectra are empty.

In this PR, I've added a boolean to chose whether or not to have this additional spectra tab in the Nuclearizer GUI. Right now I have this hardcoded in the module construct, but I can be more clever about have this option accessible if people see a use-case. I think people are only going to want to use this plotting option when doing non-standard things and it's not clear how often that would be.

I did start to explore an option to only make this TAC Cut Spectra appear in the GUI if the EnergyCalibration module comes before the TAC Calibration module by iterating through the active modules in MSupervisor. So that's a possibility, but I erred on the side of simplicity today.

Is there any way we can have this appear, once both energy and TAC calibration module are run, no matter their order?

Just to be clear, there is also an equivalent ExpoPlotSpectrum panel that comes along with the EnergyCalibration module - see the second image below. The tab/plots I'm suggesting to remove are the unpopulated ones in the from just the before/after TAC Calibration in the first image below.

Is the standard to do TAC before energy?
I always do energy before TAC 😇
I guess this ties back to #207

I'm marking this as a draft so I can add the automatic checker as to whether or not the energy calibration is run first. Since I think we want this ExpoPlotSpectrum panel showing the before/after spectrum for the TAC cut if the energy calibration is running first. Right @NicoleRodriguezCavero ?

Okay, now in the TACCalibration Module, I check whether or not the energy calibration has run, and therefore whether it makes sense to show a spectra. If the TAC Cal comes first, we only get a spectra after the ECal. If the ECal comes first, we get a spectra after the ECal, and then a second spectra after the TACCal. I think this provide the right level of flexibility for different users.

I like the way it is now: removing the expo plot if energy have not been calibrated, but keeping the current behavior if they have been :)

I also verified (on FM data 🎉) that I'm only getting the Energy Spectrum (TAC cuts) expo when running energy calibration BEFORE TAC calibration:
