JSON Import/Export for Agents

[gromdimon]

Overview

The current GAME framework lacks convenient methods to import/export agent configurations via JSON, similarly to one in the UI of GAME Sandbox.

Expected Behavior

1. Import: Enable setting up agent parameters from a JSON file exported from the sandbox.
2. Export: Allow saving the agent's configuration to a JSON file, similarly to sandbox export func.

Proposed API

• Import:

  agent.from_json(json_path)

  Sets up the agent's parameters from a JSON configuration.

• Export:

  agent.to_json(json_path)

  Saves the agent's current state to a JSON file.
