Lines for Dark Matter searches (from Lambda decays)

We are submitting four lines (two control lines with a prescale, two physics lines) to full DST BhadronCompleteEvent. The control lines have a slightly different-than-unity multiplicity because of the removal of the isolation, but we need this information for calibration purposes.

changed title from Lines for searches on DM candidates produced from B-decays when a Lambda(1520) is present [WIP] to Draft: Lines for DM searches (from Lambda decays)

changed the description

@ikostiuk @fredi we do not plan to add more lines to this module. I have removed the WIP since I saw you have labelled this MR with all-slots.
