Ability to pre-download models

[cragwolfe]

Unstructured-inference lazily downloads models which is likely the better choice for most use cases, however there are scenarios where the consumer would like to prefetch models.

Currently, this can be achieved for the default layout parser models, e.g. typically used for PDF's with:

from unstructured_inference.models.detectron2 import MODEL_TYPES
MODEL_TYPES[None]['model_path']    
MODEL_TYPES[None]['config_path'] 

but, it be nice if there was a simple function (with parameter(s) to allow warming different models) call the user could make to ensure any needed artifacts are downloaded.

get_model(model_name) will also do this... is that sufficient? We could also wrap it with a name tailored to what you're after...

Not sure if this relate to my issue but my corporate proxy blocks the http call to huggingface so i would love to use the same model I have downloaded locally https://huggingface.co/unstructuredio/yolo_x_layout/tree/main

Would it be possible ?
