bug about binsize

[YuDe95]

    const double PI = 3.14159265358979323846;
    const double frequency = 20.0; // Hz
    const double samplingRate = 1000.0; // Hz
    const double duration = 1.0; // seconds
    const size_t sampleCount = static_cast<size_t>(samplingRate * duration);

    std::vector<double> data;
    data.reserve(sampleCount);

    for (size_t i = 0; i < sampleCount; ++i) {
        double t = i / samplingRate;
        double value = std::abs(std::sin(2.0 * PI * frequency * t));
        series.push_back(value);
    }
    // RainFlow::Series series { -2, 1, -3, 5, -1, 3, -4, 4, -2 };
    auto counts = RainFlow::countCycles( series);
    double countAll;
    double rangAll;
    for(auto count:counts)
    {
        countAll +=count.second;
        rangAll+=count.first;
    }
    qDebug()<<counts;
    qDebug()<<"countAll"<<countAll;
    qDebug()<<"rang"<<rangAll/counts.size();

when you use auto counts = RainFlow::countCycles( series,1);
we can get 1,40.
when you set binSize=2
then we can get 2,40
