CPAlgorithms: add event selectors for large-R jets

We introduce event-level selectors for large-R jet collections:

• LJET_N: selects events with N large-R jets above some pT threshold
• LJETMASS_N: selects events with N large-R jets above some mass threshold
• LJETMASSWINDOW_N: selects events with N large-R jets within some mass window (or outside, with the veto mode on)
