This commit adds a torchscript version of the resnet34 breast tumor classification model.

```python
import torch
import wsinfer

w = wsinfer.get_model_weights('resnet34', 'TCGA-BRCA-v1')
model = w.load_model()
c = torch.jit.script(model, example_inputs=[(torch.ones(1, 3, w.transform.resize_size, w.transform.resize_size),)])
torch.jit.save(c, root / w.url_file_name)
```
