Error: Library "torch_wrapper_types" is private, it cannot be a dependency of a public library. You need to give "torch_wrapper_types" a public name.

```bash
# dune build examples/llama2/llama2.exe
File "src/wrapper/dune", line 20, characters 49-68:
20 | (libraries ctypes.foreign ctypes torch_bindings torch_wrapper_types)

Error: Library "torch_wrapper_types" is private, it cannot be a dependency of
a public library. You need to give "torch_wrapper_types" a public name.
```

Start with the library declarations around line 20 of src/wrapper/dune and reproduce the failure with dune build examples/llama2/llama2.exe. Check the visibility of torch_wrapper_types and make the dependency acceptable to the public library; done when that build completes without the private-library error.
