GGUF: Flux Unchained

I created the original (v1) from an fp8 checkpoint. Due to double quantization, it accumulated more errors. So I found that v1 couldn't produce sharp images. For v2 I manually merged the bf16 Dev and Schnell checkpoints and then made the GGUF. This version can produce more details and much crisper results.
