RD common builders in the ThOr framework

Replaces !1021 (closed).

This is an attempt to migrate the rdbuilder.py (the original rdbuilder.py is preserved as is for now) to the ThOr framework, simultaneously adding several new useful hadronic combiners. The dilepton builders are for now kept minimalistic without MVA as the ParticleFilterWithTMVA does not seem to be easy to port to ThOr.

I have commented out the prompt track builders and the di-pion builder, which are currently unused. Many builders are updated, in particular the dimuon builder is rewritten. Note that the dilepton builders are renamed.
