[Request]Add a checkbox for not using facial bones of openpose

[butaixianran]

There is an issue for open pose. When source image and target image are not the same style, for example. source image is a 2D cartoon one, target image is a realistic photo, facial bones of openpose gonna always make the face terrible, even after adjust the weight option.

So, the best solution when source image and target image are different styles, is just offer a choice to not use the facial bones of openpose.

They are: eye, nose and ear bones.
