Please check hooks in quanthub_download_button.module - do we need it?

Using "quanthub_download_button" and "quanthub_metadata_button" libraries you make a dependency from the modules, when the core module should be independent from the additions.

What can be done:

Option 1 (the best):
Each of the modules "quanthub_download_button" and "quanthub_metadata_button" defines own field. You don't create a template for its, just outputs "#type" => "container", "#attributes" => ..., and you use node--dataset.html.twig in the theme to provide container and other structure.

Option 2 (quick):
You move the libraries definitions to the quanthub_core module and mark outdated modules as deprecated.

Option 3 (compromise):
You don't attach the libraries here, and create a minimal template in the module. And real template and libraries attachment goes to theme.

So, I implemented option 3. Created the basic and a real template. Please check it.

You are right, we don’t need this anymore. Removed.
