Be able to read data from disk between restarts

Component

Anvil

Describe the feature you would like

Anvil will persist state to disk after hitting a certain limit. It would be nice if anvil was able to read this data / persist it between restarts. That way I could run, e.g. a game on anvil, then spin it down when it was no longer being played, and spin it up again when it was.

Additional context

I think what this would involve is:

• Ability to specify a data directory, where data is persisted (internal state, etc.)
• Reading from the data directory if path is specified (and bootstrapping state from it on startup)

Agreed. This would be super valuable for using anvil in a "full stack" development environment.
