closed form density functions as additive modifiers

[lukasheinrich]

Summary

This is a slight variation of #1991 in so far that instead of a multiplicative modifer f(pars) that is multiplied to all bins in a sample, this allows an additive modifier f(x,pars) where x is the channel observable.

This is likely a highly non-optimized implementation (esp the integration using scipy.quad and a python loop over bins), but it shows that things are possible
