[Suggestion] Auto updating for self-hosted library

[ecker00]

As suggested on Reddit, if Gogg could be used to keep a self-hosted library (RomM) up to date. Ref: rommapp/romm#720

I see quite a few things to tackle to fulfill such a role:

• Docker image, so it can easily run on a server alongside RomM
• Watcher mode which looks for updates once a day
• Output dir by platform, Romm expects each platform on ./win ./linux ./mac etc.
• Authentication on remote (as is would be running on a headless server)

Hypothetical how it could maybe work in the end:

services:
  romm:
    image: rommapp/romm # Bit simplified for demonstation
    volumes:
      - ./library:/romm/library
    ports:
      - 8080:8080

  gogg:
    image: habedi/gogg
    volumes:
      - ./library:/romm/library
    environment:
      - ACCESS_TOKEN=123 # Some method to obtain auth
      - PLATFORM_WIN=/library/win # Expected path for RomM
      - PLATFORM_MAC=/library/mac
      - PLATFORM_LINUX=/library/linux
    command: gogg watch --platform=all  --lang=en --threads=3 --dlcs=true --extras=false

Sounds like an interesting idea.

Just one thing: I think the current version of Gogg supports the watching for updates operation already, which can be achieved with something like:

gogg download --id=<game-id> --dir=<storage-dir> --resume=true --extras=false --dlcs=true

This won't download files that have already been downloaded, only the new files like patches for Windows games and updated installers for Linux and macOS.
