Expanding inputs for image tokens in LLaVa-NeXT should be done in processing

[jrp2014]

I get a warning using the example python script (num_images=1) using "mlx-community/llava-v1.6-mistral-7b-8bit":

Expanding inputs for image tokens in LLaVa-NeXT should be done in processing. Please add patch_size and vision_feature_select_strategy to the model's processing config or set directly with processor.patch_size = {{patch_size}} and processor.vision_feature_select_strategy = {{vision_feature_select_strategy}}`. Using processors without these attributes in the config is deprecated and will throw an error in v4.47.
