This PR brings a re-factor of the fitting function and related tools. The idea now is to express the fit as a sum of exponential functions of degree 1, 2 or 3 and leverage
lmfitlibrary to perform the fit. This library allows the user to fix parameters by setting up constrains (e.g., using previous cycle biokinetics), set bounds etc. It also computes r-square and other important criteria such as Akaike information criteria which can be used to select the best fit.It has been tested on Organ level (S-value) and Voxel level (S-value) dosimetry.
