Package CrypTen on PyPI

Summary:
CrypTen is now a proper [PyPI package](https://pypi.org/project/crypten/0.1/), making installation one step: `pip install crypten`.

* update readme with new installation instructions
* add logo raw link so it renders on PyPI
* update license and project url in `setup.py`
* specific version of `torch` and `torchvision` now specified in `requirements.txt` and automatically installed via pip

We can now also track installation statistics via PyPI.
