save H(R) from w90 to dft_input

[harrisonlabollita]

I've added wannier_hr to be saved in dft_input. This amounts to adding this as an entry in things_to_save. The H(R) object is relatively small to save and having access to it without needing the original seedname_hr.dat will be useful for future TRIQS applications.

Hi @harrisonlabollita,
yes we can definitely add the H(r) to the hdf5 file. I think typically we stored files that are not part of all DFT code converters into dft_misc_input so we should think about moving the H(r) there. Also please take a look at the tests. They do expect a matching hdf5 reference file, which is now of course missing the stored new entry.

And finally, it would be good to amend https://github.com/TRIQS/dft_tools/blob/3.3.x/doc/h5structure.rst with the new H(r) entry! Afterwards I am happy to merge this into unstable.

Best,
Alex

Hi @the-hampel,

Thanks for having a look at this. Moving the H(R) to dft_misc_input seems most appropriate. I'll make the corresponding changes to the h5structure.rst and update the tests accordingly.

Best,
Harry
