New sprucing lines for B -> K(*) H' (-> h+ h-) decays

• Modifed spruce_qee.py to add sprucing line for the decay B+ -> K+ H' and B0 -> K*0 H', where H' -> h+ h-
• h+ h- may be either K+K- or pi+pi-, hence no pid
• final state particles are all long tracks
• H' represents a dark boson, represented in code as KS0
• Code is based on https://gitlab.cern.ch/lhcb/Moore/-/blob/master/Hlt/Hlt2Conf/python/Hlt2Conf/lines/rd/b_to_Xdilepton_detached.py
• Here they consider: B+ -> K+ Darkboson(->ll)
• Utilising these pre exitsing builders
• Note: the builder make_btohemu was already orginally written for dilepton in final state but may also be used for our case (dihadron)
• Cuts are designed such that they are in line with Run2 stripping ... see here:
