Follow up of #751

Is your feature request related to a problem? Please describe.
I implemented a topiary query for (Catala)[https://github.com/CatalaLang/catala] but the released version only support linked grammars. Hence, it requires to maintain a fork to use.

Describe the solution you'd like
The PR #716 addresses this particular issue. It would great to have it released, and, in particular, with topiary-opam.

Describe alternatives you've considered
Currently, I fork topiary-opam and make the topiary submodule points to the dev branch.
