B2OC: b-baryon to hyperon d h line (shifters PLEASE ignore)

A prototype for b-baryon decay into hyperon D(s) h lines. The hyperon are separated by different track types of final states.

There are still some TODOs and we would optimize the cuts based on some mc samples for the next iteration.

The following decays are added:

• \Lambda_{b}^{0}\to\Xi^{-}D_s^{+}
• \Lambda_{b}^{0}\to\Xi^{-}D^{0}K^+
• \Xi_{b}^{0}\to\Xi^{-}D^{+}
• \Xi_{b}^{0}\to\Xi^{-}D^{0}\pi^+
• \Xi_{b}^{-}\to\Xi^{-}D^{0}
• \Omega_{b}^{-}\to\Xi^{-}D^{0}
• \Omega_{b}^{-}\to\Omega^{-}D^{0}

where the daughter baryon is reconstructed via:

• \Xi^{-}\to\Lambda^{0}(LL/DD)\pi^{-}(L)
• \Omega^{-}\to\Lambda^{0}(LL/DD)K^{-}(L)
• \Lambda^{0}\to p\pi^{-}

And the D meson is reconstructed via:

• D_{s}^{+}\to K^{-}K^{+}\pi^{+}
• D^{+}\to K^{-}\pi^{+}\pi^{+}
• D^{0}\to K^{-}\pi^{+} and K^{-}\pi^{-}\pi^{+}\pi^{+}
