[Request] Update m_vis pt_vis functions with more generic implementation using CombineP4s

[harrypuuter]

After #216 is merged, a generic function to combine P4s is available (lorentzvectors::CombineP4s({df}, {output}, {input}))

Using this functions, some old implementations can be removed namely

• CROWN/src/quantities.cxx

  Line 167 in a8bdbd1

  ROOT::RDF::RNode m_vis(ROOT::RDF::RNode df, const std::string &outputname,

• CROWN/src/quantities.cxx

  Line 293 in a8bdbd1

Does this intervene with any of your analyses since it will require some adaptations in the configuration @ralfschmieder @nshadskiy @nfaltermann @conformist89 ?

You will have to use lorentzvectors::CombineP4s({df}, {output}, {input}) to build the combined lorentzvectors, and then use the basic quantities::mass() functions to extract those values
