I am writing multidimensional arrays to HDF5 and I would like to make use of the HDF option to specify the datasets that contain the dimensions of the array (to be concrete, it is for instance a 3D temperature field, with other arrays `x`, `y`, and `z` that contain the respective locations of the grid points. I found some instructions on how `h5py` does it here: [Dimension Scales — h5py 3.7.0 documentation](https://docs.h5py.org/en/stable/high/dims.html) to show what I am after. How can I do this with the Julia HDF5 package?
