BnoC: HLT2 / Spruce lines: 2-/3-/4-/5-body baryonic modes

Collection of new BnoC baryonic lines, currently still work in progress.

Implemented new modules (based on the final state):

• bbaryon_to_phh
• bbaryon_to_phhh
• bbaryon_to_l0hhh
• bbaryon_to_lightbaryon_hh
• bbaryon_to_hyperon_4h

Done:

• evaluate and tune basic builders, per specific selection or per decay topology - general cuts looks suitable for all modes at this moment
• finish various missing lines - all planned modules implemented
• crosscheck overlap with already existing modules - bbaryon_to_lightbaryon_h rewritten, some modules / decay topologies could be further reorganised
• evaluate full rates - resulting rates listed on the bottom of the description

Future plans (outside of the scope of this MR)

• crosscheck with the topo lines - on hold until (mostly) final topo tuning for 2023 and later for 2024+
• based on previous step look on simple MVA-preselection per decay topology - more a long term work for a few months, first steps already ongoing

Resulting rates:

• rates were obtained using upgrade_minbias_hlt1_filtered sample, thus all the values should represent an upper limit of possible rates
• only lines with non-zero rates are listed (using 2023 reconstruction sequence):
