Unfolded Add Node in Network Graph related to the rounding

[ahmad-mirsalari]

I have noticed an issue in the commit (e8cfc0d), specifically in the graph of the network.

There is an Add node for rounding (0.5), which should ideally be folded together with the other Add node before it. This seems to be causing a discrepancy in the network graph.

Could this be checked and corrected?

Thanks for looking into this.

Hi @ahmad-mirsalari!
I believe this is in issue of oversight. For PULP-NN type quantization, the rounding offset (eps/2) is indeed added to the bias of the requantization operator. For CMSIS type quantization, this is not done, since the kernels work differently. I'll look into a fix with @da-gazzi.
