OpenCV Image WarpAffine equivalent.

[vpenades]

In SciSharp tensorflow, is there a equivalent to OpenCV's Image WarpAffine method?

This method essentially copies an image applying a matrix transform. The practical effect is that you can copy an image aplying a scaling, rotation and translation in one shot.

We want to use a few models where the input tensor requires not only to be scaled from the source image, but also rotated to align with some previously computed features.

@vpenades All the APIs related to image transformers should be list here: https://www.tensorflow.org/addons/api_docs/python/tfa/image

I seems the method I need is this one: https://www.tensorflow.org/addons/api_docs/python/tfa/image/transform

But is it available from the c# binding side?

[Oceania2018]

This PR includes many image related APIs but seems not include transform. I will add to my todo list.

It would be great if you can contribute this API.

To tell you the truth, I'm just new to SciSharp TensorFlow, and I have zero knowledge of python (I guess it's about time to kick my own butt and learn it once and for all), The previous PR about the unit tests was a no brainer, but I am not confident enough to include such an API... I have no idea where would I need to begin with...
