bug in layer graph construction about openvino2tensorflow

[PINTO0309]

This is the first time I have received such a detailed and thorough proposal. Thank you very much.
I will try your suggested modifications in the next update. :)

Incidentally, openvino2tensorflow is a tool I dared to start making to compensate for the low conversion performance of onnx-tensorflow, but I made it blindly without much ML knowledge. Thus, the abundance of optimization features is proportional to the low quality of my program.

I myself recognize that the workload required of users is very high due to the abundance of features and error handling. Thus, I have recently started building a new tool that incorporates all of my 2-3 years of model conversion experience.

It is probably the most efficient optimization tool among the various tools I have created, and yet it has the lowest conversion error rate.

Instead of updating openvino2tensorflow a little less frequently using my private work time, I try to devote as much time as possible to updating onnx2tf. If you are interested, give it a try, I think it is easier than openvino2tensorflow.

Again, thanks.
