WIP: Update JetUncertainties to calculate inefficiency SF
Updates to follow up !31202 (merged)
- Added a new configurable flag m_calcBkgIneffSF. If it is set to 0, inefficiency SF is not calculated for single q/g and "other" background components (SF=0 is returned).
- Added a new function to calculate the uncertainty on the efficiency value and propagate it to the inefficiency SF.
