Some generators, e.g. KKMCee, do not provide support for a non zero crossing angle.
We need a component that, added in between the generator and the detecor simulator, boost the produced particles of the right amount required by beams crossing angle.
We should investigate if this can be used for beams energy spread and other beam related quantities.

There is a component in DD4hep that does this:
