Bug in GLPDepth/code/dataset/nyudepthv2.py file

if the scale_size is true, 
the depth is resized with image data and not depth data.  

Following is the code snippet:

```
if self.scale_size:
            image = cv2.resize(image, (self.scale_size[0], self.scale_size[1]))
            depth = cv2.resize(image, (self.scale_size[0], self.scale_size[1]))
```
