Issue DM-5353: Upgrade minuit2
Minuit2 5.34.14 came out in 2014. The current version in the stack is 5.28 from 2010. Minuit2 is annotated on the DM third party software page as being approved for 6-monthly uprev. Minuit2 is only used by AFW. Release notes for 5.34.14: * Several fixes and improvements have been put between this verion and the previous stand-alone one (5.28). Main new features is now the support for using the {{ROOT::Math::Minimizer}} interface via the class {{ROOT::Math::Minuit2Minimizer}} also in the standalone version. A new test has been added ({{test/MnSim/demoMinimizer.cxx}}) to show this new functionality * Other major improvements is in the control of the error messages. One can now use the class {{MnPrint::SetLevel(int value)}} to control the output level. The same can be achieved by calling {{ROOT::Math::Minuit2Minimizer::SetPrintLevel}}.
