    Description

      For now BaggingUpstreamTransformer makes upstream sequential to make transformation deterministic. Maybe we should do it other way, for example use mapping of the form (entryIdx, en) -> Stream.generate(() -> en).limit(new PoissonDistribution(Well19937c(entryIdx + seed), ...).sample())
