[REQ] depfillv2

After some inactivity, it would be interesting to add "Free-Form Image Inpainting with Gated Convolution" (aka deepfill) Pytorch implementation by @csqiangwen:

https://github.com/csqiangwen/DeepFillv2_Pytorch

...seems that @vrindaprabhu  already implemented it here:

https://github.com/vrindaprabhu/deepfillv2_colab/

Hope that inspires !
