How to support new operators

1. Add onnion_runtime/xxx.py

• An onnx operator Xxx must correspond to a class Xxx.
• A class Xxx must implement __init__ and run methods.
• The parameters of the __init__ methods must be self, opset_version, and kwargs.
• The attributes of the operator must be passed through the kwargs of the __init__ method.
  • Get the required attributes by kwargs['attr_name'].
  • Get the optional attributes by kwargs.get('attr_name', default_value).
• The inputs of the operator must be passed through the arguments of the run method.
• The run method must return the list of np.array.

2. Add from .xxx import Xxx # noqa: F401 to onnion_runtime/__init__.py
3. Update "Supported Operators" in README.md
4. Add tests/test_xxx.py
5. Run tests poetry run pytest -v
6. Format and lint poetry run pysen run format && poetry run pysen run lint
