Title: import radiativeZ filter

- clone of PR #4433

- purely the forward port of #1101 , which enter 62x and was not fw-ported to 70-71x

- import radiative z filter approx 6% selection efficiency on ZMM_8TeV

- needed (also) for d.v.mc exercise, to economize GEN-SIM production of z mu mu gamma events
