Inversion in case of negative features now deals correctly with the
calculation of parameters, in particular fluxes.
Introduced a new bool flag to the Detection class that records whether the
source is a positive or negative feature. If negative, the peakFlux parameter
is the minimum flux (most negative), else it is the maximum/most positive flux.
