OnnxConfig for LayoutLMv2

Hello,

Did anyone try approach to making onnx config for LayoutLMv2? What do you think is it possible?

Thanks.

It would be really cool to have ONNX support for LayoutLMv2!

I haven’t looked into ONNX yet, but I assume it should be possible.

Would be cool if you make a PR for this. You can take a look at the documentation to get started.
