The ITS reco cuts used for PbPb are currently defaults in the compiled code and they are too strict for pp.
This will relax the ITS track-length-dependent pT cuts and remove restriction for starting layer added for PbPb.
Also will impose TPC matching starting from pad-row 78, like in PbPb

For the record: some comparison of pp-anchored MC performance (LHC24af_550916) with different settings :
like PbPb (both ITS reco: MinPt: NC7:0.08 NC6:0.20 NC5:1.00 NC4:0.17, 4point tracks can start from Lr0 and Lr3 only + matching starting from PR78)
old pp ITS reco but with matching from PR79
tuned ITS reco with less strict cuts than in PbPb to minimize fakes (MinPt: NC7:0.05 NC6:0.09 NC5:0.17 NC4:0.13, starting layers requirements like in pbpb) : used in this PR.

K0s with global and any tracks: "tuned" has a tiny advantage over old pp in the glo, while the latter shows a better integrated result.

Probability to match TPC track (min 60 clusters, |dca|<6 and |tgL|<1 to ITS: the tuned one has a tiny edge

Number of PVs and their contributors distribution (all and globals only): tuned one produces most of PVs (tiny difference) but in average has more global contributors.
