Add stat uncertainty and rebin options in plotter

[jeyserma]

Added options to plot the stat uncertainty (sig, bkg, sig+bkg) and optional uniform rebinning

Hello @jeyserma,

do you have any example plot?

[jeyserma]

An example of using the stat unc and rebinning is given in examples/FCCee/higgs/mH-recoil/mumu/analysis_plots.py:

plotStatUnc = True
rebin = [1, 1, 1, 1, 2] # uniform rebin per variable (optional)

OK, I generated it :)

I find it a bit hard to read, maybe increase the pitch of the diagonal lines or use just solid grey?

@BrieucF What do you think?

[BrieucF]

Yes, the example I pointed in the FCCSW forum thread [1] is obtained with something like:

stat_and_syst->SetMarkerSize(0);
stat_and_syst->SetMarkerStyle(0);
stat_and_syst->SetFillStyle(3154);
stat_and_syst->SetFillColor(42);
stat_and_syst->Draw("E2 same");

Some inspiration could probably be taken from [2].

Updated the hatch spacing. The PNG is always horrible, but PDF looks good.
