[Typo] Possible error in model_type from LTXV base model

### Expected Behavior

Maybe I'm wrong but the `model_type` from from the LTXV class init (`model_base.py`) is not `ModelType.FLUX` but `ModelType.FLOW` ?
```
class LTXV(BaseModel):
def __init__(self, model_config, model_type=ModelType.FLOW, device=None):
super().__init__(model_config, model_type, device=device, unet_model=comfy.ldm.lightricks.model.LTXVModel) #TODO
```

### Actual Behavior

The current implementation is:
```
class LTXV(BaseModel):
def __init__(self, model_config, model_type=ModelType.FLUX, device=None):
super().__init__(model_config, model_type, device=device, unet_model=comfy.ldm.lightricks.model.LTXVModel) #TODO
```
