Additional functions for hadronic recoil quantities

[moritzmolch]

This pull request introduces functions to calculate quantities, which are related to the hadronic recoil in an event.

• hadrecoil::scalar_ht takes a jet pt column and a column with indices of selected jets as input. The output is the scalar sum of the magnitude of the transverse momentum of the selected jets.

• hadrecoil::vectorial_mht takes a jet pt column, a jet phi column and a column with indices of selected jets as input. The output is the negative vectorial sum of the transverse momentum vectors of the selected jets.

TODOs:

• [x] add documentation strings to the new functions
• [x] Add producers to the python configuration

[moritzmolch]

Producers have been added to the config via this pull request: https://github.com/KIT-CMS/TauAnalysis-CROWN/pull/50.

@harrypuuter I added your suggestions, the compiled binary runs on a DY sample without errors. I still have to check if the functions' outputs are reasonable.

Thanks for all the checks @harrypuuter ! As it is now this PR would only be merged to my nmssm_devs branch. I guess we could merge it directly into the main branch, since nothing directly related to the NMSSM analysis is involved in the code changes.

[harrypuuter]

yes, i would merge this directly to main as well
