B&Q: Spruce: add hlt2_filter as input to certain Sprucing lines
adding specific hlt2_lines to filter on.
- filter on 'Hlt2_JpsiToMuMuDetached' and 'Hlt2_Psi2SToMuMuDetached' for 'automatically created' 'HbToPsiX' lines and several individual B->psiX lines.
- filter on
Hlt2BandQ_B*ForSpectroscopy(SL)
lines for 'automatically created' lines 'BX' (see !2234 (merged)). Right now it uses a cocktail of lines to filter on, so in principle further optimization is possible (though less trivial).
