v 1.0.0 fast style transfer

It is the stable version of fast style transfer!

What is different between this one and other fast style transfer repo:

1. It implements state-of-the-art CNN architecture for stylizing given content images.
2. It adds two additional loss items for more stable output: consistency loss and tv loss.
3. The size of the style transfer neural network is incredibly small, with only 7 MB.
4. The code supports the latest PyTorch version (aka. PyTorch 2.0).
5. This code uses a command line argument as input, which is easier and more friendly for those who are new to Python.
