Future LQ optimizations

I wanted to list here ideas for possible future LQ optimizations that could be investigated: - Handle negative bins differently in lq_cut and instead of setting them to, add a constant and subsequently fit a gaussian + flat bkg(with hight of added constant) -> should improve run wise lq estimation. Additionally one could decrease bin size. - Instead of the fit during the ctc correction do a peak width minimization similar to the aoe approach - Instead of doing the sideband subtraction apporach, fit DEP and sidebands in a combined fit so that the DEP contains a signal component and a background component that originates from the sideband fits
