Charm Hlt2 Lines for c-baryon to hyperon TT

To be ran with Rec!3438 (merged) !2367 (merged) lhcb-datapkg/ParamFiles!62 (merged)

Hlt2 lines for \Xi_c^0\to\Lambda K^-\pi^+, \Xi_c^0\to\Xi^-\pi^+, and \Xi_c^+\to\Xi^-\pi^+\pi^+ processes, with \Xi^-\to\Lambda\pi^- and \Lambda is reconstructed by t-tracks. The code structure follows that in hyperons.py.

The LambdaTT combinations follow the !1873 (merged) but with a tight cut in LambdaTT reconstruction. The changes in V0_to_TT_builders.py are reported in !2242 (merged).

The rates are estimated according to the minbias_hlt1_filtered samples.

rate Hlt2Charm_Xic0ToL0KmPip_TT_DD
#= 365988.0 Sum= 19.0 | rate = ( 51.9 +/- 11.9 ) Hz

rate Hlt2Charm_Xic0ToL0KmPip_TT_LL
#= 365988.0 Sum= 32.0 | rate = ( 87.4 +/- 15.5 ) Hz

rate Hlt2Charm_Xic0ToXimPip_TTD_D
#= 365988.0 Sum= 6.0 | rate = ( 16.4 +/- 6.7 ) Hz

rate Hlt2Charm_Xic0ToXimPip_TTD_L
#= 365988.0 Sum= 9.0 | rate = ( 24.6 +/- 8.2 ) Hz

rate Hlt2Charm_Xic0ToXimPip_TTL_L
#= 365988.0 Sum= 6.0 | rate = ( 16.4 +/- 6.7 ) Hz

rate Hlt2Charm_XicpToXimPipPip_TTD_DD
#= 365988.0 Sum= 0.0 | rate = (  0.0 +/- 0.0 ) Hz

rate Hlt2Charm_XicpToXimPipPip_TTD_LL
#= 365988.0 Sum= 6.0 | rate = ( 16.4 +/- 6.7 ) Hz

rate Hlt2Charm_XicpToXimPipPip_TTL_LL
#= 365988.0 Sum= 5.0 | rate = ( 13.7 +/- 6.1 ) Hz

Here the 0 rate in Hlt2Charm_XicpToXimPipPip_TTD_DD is due to the low efficiency.
