Add electrons with brem

The FunctionalParticleMaker does not have an option to include Bremsstrahlung recovery, as needed for electrons.

The current plan is to add a new ParticleWithBremMaker that creates particles including brem corrections, taking as input the particles created by FunctionalParticleMaker and a list of photons. The BremAdder tool will be used for the brem finding and particle momentum correction. It has to be made thread safe and modernised.
