Prompting & Prompt Weighting in Diffusers

Hugging Face Diffusers Prompt Weighting:

1. **Compel Syntax**: Use the Compel library for precise prompt weighting
2. **Numerical Weights**: ("keyword")1.5 for emphasis in Compel
3. **Blend Operations**: Combine multiple prompts with weighted blending
4. **Conjunction Prompts**: Generate images that satisfy multiple conditions simultaneously
5. **Per-Token Control**: Weight individual tokens differently within a prompt
6. **Pipeline Integration**: Works with StableDiffusionPipeline and StableDiffusionXLPipeline

```python
from compel import Compel
compel = Compel(tokenizer=pipe.tokenizer, text_encoder=pipe.text_encoder)
prompt_embeds = compel("a cat++ playing with a ball--")
```
