Give generators access to screens

[vesturo]

• Currently only Serializers / Deserializers can see the screen
• Implementing this would mean Generators can take in Data from VRChat (ex. Shadermotion) and convert it into HNode Data internally, freeing up a lot of UV space

Issue opened because of Conversation on Bluesky

I think ideally what I want to do instead of this, is make it so serializers/deserializers can have multiple at a time
