Add a cache_dir argument in load_pretrained_model

[camillecochener]

Hi 👋 would it be possible to add a cache_dir argument in the load_pretrained_model() method in llava.model.builder please?
As in the from_pretrained method : cache_dir (str, optional) – Path to a directory in which a downloaded pretrained model configuration should be cached if the standard cache should not be used.
Thanks !
