Any plan to support Graph attribute type?

[odannyc]

I'm trying to run a custom model but I'm getting an error when trying to load the model.

onnx: operator . Implementation error for attribute body (&ir.AttributeProto{Name:"body", RefAttrName:"", DocString:"", Type:5, F:0, I:0, S:[]uint8(nil), T:(*ir.TensorProto)(nil), G:(*ir.GraphProto)(0x14000134180), Floats:[]float32(nil), Ints:[]int64(nil), Strings:[][]uint8(nil), Tensors:[]*ir.TensorProto(nil), Graphs:[]*ir.GraphProto(nil), XXX_NoUnkeyedLiteral:struct {}{}, XXX_unrecognized:[]uint8(nil), XXX_sizecache:0}): ir.AttributeProto_GRAPH not handled yet

The error is coming from: https://github.com/owulveryck/onnx-go/blob/13f8618fa3024b5a5b65e03d501985bede0b7f31/attributes.go#L32-L36

Are there any plans to support this?
