Consider simplifying expression after generation for optimization

[OleksiiBulba]

Generated expression contains nodes that can be simplified on it's own before the image generation. Example, on this screenshot

we see a bunch of nodes that can be simplified to NK_NUMBER.

Or write a grammar that doesn't produce these expressions (random cannot show up on both sides of an add or mult operation etc..)

Or you can do the optimization at the level of the fuzzer to "inline" the result of the operation

I think it would be hardest to do optimization at the level of the grammar, rewriting the grammar so that no path can lead to unoptimized results

Just thoughts
