Add Nvidia NitroGen to huggingface diffusers

[AffanBinFaisal]

Feature request
NVIDIA's NitroGen is a groundbreaking AI model designed to play hundreds of video games autonomously across various genres. This model, developed in collaboration with MineDojo, is trained on over 40,000 hours of publicly available gameplay videos, allowing it to perform across 1,000+ games without relying on proprietary tools or custom datasets.

Motivation
This model should be added to Hugging Face Transformers so that developers can use it through the HF interface and fine-tune it to play other games. Doing so will also help researchers build further on this work.

Your contribution
Sure, I’ll try to help with some modules, though I’m not entirely sure yet.

I opened this issue in huggingface transformers as well, but a developer said it's more suitable in diffusers.
