contribution of a PaddleSeg onnxruntime C++ sample

[xmba15]

Hi PaddleSeg's dev team. Thank you for the great repo.
I created a C++ onnxruntime app sample for model trained by PaddleSeg. It took me some time to figure out how to use onnxruntime cpp to serve the model. So maybe some others can somehow know how to use PaddleSeg onnx cpp from this app:

Firstly, thanks for your contribution.
You can create a folder named 'onnxruntime_cpp' under PaddleSeg/deploy/ and push the demo to the folder. Please refer to the cpp demo and make the demo concise.
Once you create a PR, we will review and merge it.
Thank you again.
