Updated the Mandic Trapping Model used in Allpix2
Current Mandić Trapping model used in Allpix2 is based on the parameterization from the paper https://iopscience.iop.org/article/10.1088/1748-0221/15/11/P11018. However, there is an error with the power function fitting, the scaling factor should be 540ps instead of 54ps, see the erratum from Prof. Mandić https://iopscience.iop.org/article/10.1088/1748-0221/16/03/E03001. Hence, the corresponding model model in Allpix2 should be "tau_eff_electron_ = 0.54 * pow(fluence / Units::get(1e16, "/cm/cm"), -0.62);" instead of "tau_eff_electron_ = 0.054 * pow(fluence / Units::get(1e16, "/cm/cm"), -0.62);"
