[FEAT] Stop cuebe from rendering manifests when ignore attribute has been set

[astraios]

Is your feature request related to a problem? Please describe.
When I want something to be excluded, cuebe still tries to render the structure, yes it won't produce manifests BUT if
I'm trying to troubleshoot something specific and want to exclude something else to keep thing simple or avoid useless noise, or if I'm surrounded by bugs everywhere and would like to focus on just one thing, I wish we had the capability to stop cuebe from rendering manifests (before even extract).

I actually don't know exactly when the unification and checks for concrete values happen in the code.

Describe the solution you'd like
Either by default or enabled by a command line arg?
