Deprecate `Mat.shape` or make it as an alias of `Mat.size` #232

          > How can I use Mat.size in Dart to handle 3D Mat data? Could you give me some more suggestions? I'm sorry, but I'm not familiar with C++ at all.

Refer to the API doc, https://pub.dev/documentation/opencv_dart/latest/cv.core/Mat/size.html , Mat.size will return a VecI32, basically you can use it as other Iterable like List.

But Mat.shape may be misleading and we will make it as an alias of Mat.size in the future.

I have reconsidered this, and think it's not necessary now.

2D mat is the most commonly used, and many users have used Mat.shape, keeping compatibility is important.

for 3D mat, just use Mat.size, same as opencv c++.
