RD: add BTohhGamma_GammaToEELL lines
- HLT2 lines to select B->(Kpi,KK,pipi,pK)gamma for LL converted gamma + corresponding sprucing lines to run on output of Hlt2RD_BToHHGamma_GammaToEE once it is optimised
- Adding brem to gamma_to_ee builder and tightening selections
Rates and efficiencies
Assuming input rate = 1.14MHz
MB input sample = 100K expected_2024_min_bias_hlt1_filtered

HLT2 inclusive full-stream lines (modified builders)
Line | Old Rate / kHz | New Rate / kHz |

Hlt2RD_BToHHGamma_GammaToEE_InclDecision | 0.89 +/- 0.1 | 0.25 +/- 0.05 |
Hlt2RD_BToHHHGamma_GammaToEE_InclDecision | 0.62 +/- 0.08 | 0.18 +/- 0.05 |
Sprucing lines (added lines)
Rates not tested but very low rates expected: 100 Hz in case of full overlap between the new sprucing lines selection and the inclusive ones they sit on top of. Overlap may be low-ish, so 10Hz addition is more realistic. Quite well motivated: we need to validate the inclusive lines behaviour and these are the first sprucing lines on top of the converted photon radiative inclusive lines targeting converted photons.
