Writing group attribute with H5easy

[aborzunov]

My attempt was resulted in IOT instruction

{
    auto filepath = std::string("./tmp.h5");
    auto file = H5Easy::File("example.h5", H5Easy::File::Overwrite);


    auto data = std::vector<double>(50, 42.0);
    H5Easy::dump(file, "/group1/group2/data", data);

    H5Easy::dumpAttribute(
            file,
            "/group1",
            "description",
            std::string("group desction"));
}
