2FA exprires after each docker restart

## Summary
2FA exprires after each docker restart


## Context
I'm running icloudpdf as docker on a linux machine. Every time I restart the docker container the tool requires me to authenticate again.

I'm currently mounting only the `/data` folder

```
    volumes:
      - /home/me/icloud-photos:/data
```

Is the tool storing a cookie or similar somewhere that I should also mount on the host?
