Subject: [PATCH] fix(setup): Update Physionet 2017 challenge download links
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

### 🔨 Motivation
The original download links used in `setup.sh` for the Physionet Challenge 2017 data were broken and failed to complete the script's execution. This prevented users from successfully setting up the necessary training and sample datasets.

### ✅ Changes
This pull request updates the `setup.sh` file with the new, working, direct download URLs for the following files:

* `training2017.zip`
* `sample2017.zip`
* `REFERENCE-v3.csv`

The script now uses the direct `?download` links from PhysioNet, ensuring the setup process completes successfully.

### 🧪 Testing
The updated `setup.sh` script was executed locally to confirm that:
1.  The `data` directory is created.
2.  All three files (`training2017.zip`, `sample2017.zip`, `REFERENCE-v3.csv`) are downloaded correctly.
3.  The two zip files are successfully unzipped.
4.  The script proceeds to the final step (`python build_datasets.py`) without errors.
