Network optimization (Simplification - Simplify)

[i3130002]

Is your feature request related to a problem? Please describe.
While using the module, I noticed that it would not reduce the nodes and optimize/simplify the networks. It might be a great idea to do so especially after training and before exporting the top one.

Describe the solution you'd like
Suppose we have a network for XOR similar to the image below

This network can be optimized into something more standardized like this image from here

Describe alternatives you've considered
A method to perform optimizations on a network or as a step in evolution.

Additional context
Years ago I witnessed a (Java if I'm not mistaken) neat project doing so.
