Split ttool search output by ttools and loki functors
Including variable names in the tuple tool search functionality !90 (merged) and https://gitlab.cern.ch/lhcb-dpa/wp6-analysis-preservation-and-open-data/lhcb-ntuple-wizard/-/merge_requests/54 fixed a bug in embedding.json where LoKi functors with the same definition as other functors are now included. Previously the definitions were used as the keys in embedding.json, and were therefore not duplicated.
Now that many more LoKi functors are exposed to the frontend search function, they tend to dominate the search output. Therefore, I think this feature would be more useful if we split the output into top 5 hits for tuple tools and LoKi functors separately.
