I think there is a littlr error in CPUDetectionOutput.cpp in backend folder

在输出检测框阶段，outPtr已经是float型了，为啥还*4呢？
// write data
auto outPtr = output->host<float>();
for (int i = 0; i < numDetected; i++, outPtr += 6 * 4) {
    auto box      = allClassBoxes[i];
    outPtr[0 * 4] = box_label(box);
    outPtr[1 * 4] = box_score(box);
    outPtr[2 * 4] = box_rect_xmin(box);
    outPtr[3 * 4] = box_rect_ymin(box);
    outPtr[4 * 4] = box_rect_xmax(box);
    outPtr[5 * 4] = box_rect_ymax(box);
}

因为是在通道上做了pack 4
