ClusterCompressionStudy

Code was mostly written by claude.

Two patches are added for alidist (dependecies) and O2 (cluster binary dump).

To get the comparision compression ratio for the TopoDict, treat every cluster as huge -> full pattern is written out, then: unc = TotBytest without Topo

root [1] a = o2sim->GetBranch("ITSClusterComp")
root [2] a->GetTotBytes("*")
(long long) 358269474
root [3] b = o2sim->GetBranch("ITSClusterPatt")
root [4] b->GetTotBytes()
(long long) 198774260

com = ZipBytes with Topo

root [4] a = o2sim->GetBranch("ITSClusterComp")
root [5] a->GetZipBytes("*")
(long long) 280954970
root [6] b = o2sim->GetBranch("ITSClusterPatt")
b = o2sim->GetBranch("ITSClusterPatt")
root [7] b->GetZipBytes("*")
(long long) 13719564

(358269474 + 198774260) / (280954970 + 13719564) = 1.89
