OstapHEP/ostap: v1.9.6.4

v1.9.6.4 New features: add += and -= operators for Ostap::Math::HermiteSum re-introduce ostapfitting.funbasic.func_factory for better backward compatibility add forward declarations for Karlin-Shapley and Karlin-Studden add more constructors to Ostap::Math::Polynomial add conversion from Karlin-Shapley and Karlin-Studden polynomials into regular polynomials add more contructors to Ostap::Math::Polynomial class unify the key-function for case-insensitive (and no underscores) dictionaries improve ostap.fitting.roostats and corresponding test more polishing for ostap.fitting.roostats and corresponding test disable plot from Feldman-Cousins for ROOT<6.18 for ROOT>6.18 for ROOT.RooArgSet extend contains and getitem to accept indices and slices add generic fixed shape (no parameters) as RooAbsReal add fixed shape from histogam (no parameters) as RooAbsReal more polishing for ostap.fitting.roostats and corresponding test add front,back and pop methods add Karlin-Shapley and Karlin-Studden parameterisation for histograms remove some script from scripts subdirectory add more wrappers and utilites for RooStats (many thanks to Dmintry Golubkov for his examples and slides) extend test_fitting_roostats to cover intervals, point limit, scans - including constraints, resolution and efficincies that depends on ovservables Add Ostap::MoreRooFit::Minimal and Ostap::MoreRooFit::Maximal add ostap.roostats.FrequentistCalculator extend the test for FrequentistCalculator add more efficient integration for Shape1D/Shape2D/Shape3D/Histo1D/Histo2D/Histo3D classes add tag parameter for Shape1D_pdf/Shape2D_pdf/Shape3D_pdf 1, improve test_fitting_roostats.py Backward incompatible: Bug fixes: fix thisostap.sh for usage with zs
