RD - Adding custom BDTs and updating working points for b->sll MVA lines
Dependencies
This MR depends on:
lhcb-datapkg/ParamFiles!92 (merged)
which is the one containing the BDT XML files
Purpose
This MR will:
- Train a BDT per process using Run3 simulation and real Run3 data.
- Update the working points such that the misid and same sign lines will be prescaled when needed, while lines targeting signal will have their BDT WP uptimized.
