h5_write and read for QDiag Tensor


I see that h5_write and read are not implemented for QDiag tensor both in C++ and Julia. Is there an easy way to add this feature in my code. I tried to overload the function

template<typename V>                                                                                                             
void h5_write(h5::group parent, std::string const& name, QDiag<V> const& D)

but somehow doTask does not recognize that.

Thank you,
