MaskRcnnMindsporePost

This is the MaskRcnnMindsporePost model postprocessing class, which is inherited from the object detection postprocessing base class (ObjectPostProcessBase).

The Init(), DeInit(), and Process() APIs of ObjectPostProcessBase are reloaded (see the description of ObjectPostProcessBase). The assignment operator "=" is also reloaded.

In addition, it implements the std::shared_ptr<MxBase::MaskRcnnMindsporePost> GetObjectInstance() method to obtain the smart pointer instance of this class.
