how to use flux loras with text encoder keys with diffusers?

resulting lora weights from setting train text encoder to true is incompatible with diffusers load_lora_weights. the script networks/convert_flux_lora.py does not convert the text encoder keys either.

Start with networks/convert_flux_lora.py and trace how it handles LoRA keys when the text encoder is trained. Compare the resulting keys with the format expected by diffusers load_lora_weights. Done means converted weights that include compatible text encoder keys and can be loaded successfully.
