1. Add FaceAttribute Edit with sliders

Egs: this is zhoumo is smiling.

By Add ctrl Lora to support lora prompt like this ,which mean，during the sampling process, the amplitude of LoRa is controlled by a piecewise linear function input_prompt += f"<lora:{feature_edit_id}:0@0, 0@0.5, {feature_edit_id_ratio}@0.5, {feature_edit_id_ratio}@1>, "
