Can't convert keras model with input dtype=tf.string #613

Regarding the issue that was asked on onnx/onnxmltools#252

Is this added or planned for keras2onnx? I have tested with version 1.7.1 of onnx2keras and still get the issue in the topic.

Seems that tf.string input type is not supported until onnx opset 13 which has not been released yet. So onnxruntime does not support it right now so it cannot run. We will add this feature after it is getting supported.
