Description

Add default models to the docker image. The models are on the order of 100MB in size for pvnet and the summation model. The models will be saved to the on-disk model cache and this means we do not need to download them from huggingface each time we run the app.

This seems neater and makes us less susceptible to rare huggingface outages, as happened today.

Did you try it locally? did it work?

[dfulu]

Yeh, I ran the container locally and it works. Doesn't need to download the model in the app anymore
