eflowRec: skip thinned taus in PFTauFEAssoc
Hello,
This MR is a follow-up of !44978 (merged) that introduced a dynamic variable to indicate whether a tau will be written to AOD. The variable is now exploited in PFTauFlowElementAssoc where thinned taus can be skipped. It should hopefully address both the CPU increase reported in ATLASRECTS-6412 and the invalid element links reported in ATLPHYSVAL-771.
Tagging @mhodgkin for blessing.
Cheers, Bertrand
