PyTorch Implmentation of triplet loss

[KinWaiCheuk]

Hi Olivier, I contacted you almost two years ago regarding the PyTorch implmentation. Now I have finished rewritting your code in PyTorch.

Would you like me to have a pull request so that your code contains both tensorflow and pytorch implmentation?
Sorry about that I didn't not fork your repo two years ago, I was still a noob in github at that time.
