[false issue]can not load from file

[myheren]

I am using the following code to test this package。Notice that I used a different name in EigenHDF5::load, it won't work out and I get an IO exception:

Eigen::Matrix<long double, Eigen::Dynamic, Eigen::Dynamic> mat(3, 4), mat2;
    mat << 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12;
    std::cout << mat << std::endl;
    {
        H5::H5File file("test_MatrixRoundTrip_LongDouble.h5", H5F_ACC_TRUNC);
        EigenHDF5::save(file, "longdouble_matrix", mat);
    }
    {
        H5::H5File file("test_MatrixRoundTrip_LongDouble.h5", H5F_ACC_RDONLY);
        EigenHDF5::load(file, "mat", mat2);
    }

Exception is ：

HDF5-DIAG: Error detected in HDF5 (1.8.19) thread 0:
  #000: H5D.c line 356 in H5Dopen2(): not found
    major: Dataset

I think the tests in this package do not really pass because if you use the same longdouble_matrix name when you load from "test_MatrixRoundTrip_LongDouble.h5", then I think you are using the same matrix when you saving to file and the data is never loaded from file.

sorry, I am new with hdf5, I understand this name means dataset name now.
