@jingan-181 Could you please also solve the issue of #2899 by this refactor. After this, we will be able to add a case test in the CI workflow. Thanks.

I think that the Wannier90 interface refactor in this pull request resolves issue #2899. I have provided an explanation for the file inconsistency under different CPU cores in issue #2899.

@jingan-181 do you need any help for CI tests failure?

[jingan-181]

@dyzheng Can I do CI testing under my repository branch? If possible, how to perform CI testing?

[dyzheng]

Thanks for your contribution!

There are still works to be done after this PR:

1. add doxygen format annotation in .h files.
2. add at least 3 test cases in examples or test/integrate for
   • LCAO with wannier_method =1 ;
   • LCAO with wannier_method =2 ;
   • PW with wannier_method =1 .
