This introduces: * asyncronous event generation * possibility for parallel event generation This is useful for: * hiding latency (IO) of certain generators * decoupling the actual work from the call sequence into HybridGenerator * collaboration from multiple clones of the same generator to generate a certain number of events The implementation relies on tbb::task_arena and input/output queues for decoupling the task_arena from the HybridGenerator thread. Small adjustments to seeding of Pythia8 in order to avoid same seeds in multiple parallel Pythia instances.
