Draft: Read VELO hit efficiencies in the digitisation
This MR includes the changes needed in the VPDigitCreator to remove hits according to an efficiency map in SIMCOND. The efficiency map is only included in simcond for now, with dd4hep for later this year.
Right now still a draft, running tests.
Goes with: lhcb-conddb/SIMCOND!241
