Torchsnooper

- Add support for named tensor.

Remove f-string to improve compatibility on older python 3.

Improve support for integral and boolean tensors: On some versions of PyTorch `torch.isinf` and `torch.isnan` does not support integral or boolean tensor well, this leads to `REPR FAIL` in TorchSnooper. This problem is fixed in this version.

The output of `snoop` verbose mode is improved

Add [snoop](https://github.com/alexmojaki/snoop) support.

TorchSnooper now reports `nan` and `inf` when detected.
