Add a Python function capable of translating a namespaced Rucio dataset/file to the absolute path on the local filesystem of the datacenter (e.g., HPC) on which the code is currently running.

Sth like namespace_to_path('jdoe:physics_dataset') returning:

• '/dacache/slling.si/.../physics_dataset' when on HPC1
• '/other/path/.../physics_dataset' when on HPC2

The dataset can or cannot be on the HPC:

• When the dataset is available on the local RSE, return a list of paths to the dataset files (or just the path to the root directory of the dataset, if you prefer).
• When the dataset is not there, create a Rucio rule for async copy of the dataset and raise a custom exception to inform the user that the dataset is not present at the moment and that the job cannot continue, although a rule has been created.

How to proceed;

• Create a rucio.py module under src/itwinai/ to store the python function meant to convert a rucio dataset to the absolute path on the local RSE
• Add tests in a test_rucio.py file under tests/

Once this is done, we will integrate it with other itwinai modules (e.g., config parser and CLI)
