Cyclical link dependencies FastJet addon <-> FccAnalyses?

[vvolkl]

The FastJet addon uses symbols from JetClusteringUtils.cc (here for example) and should actually link to the FccAnalyses target where JetClusteringUtils.cc is built.
But the FccAnalyses target links against the FastJet addon here.

Not sure why the linker does not complain ( it does with apple-clang 16 on macos, where I noticed this). Maybe JetClustering.cc should be moved back to analyzers/dataframe?

I have also found this issue. This should indeed by fixed if we want to compile on MacOS. The options are either to move back JetClusteringUtils.cc to analyzers/dataframe or create an additional library with jet clustering utilities that could be linked in the FastJet plugin.
