Describe the feature you'd like to request

Current input looks something like:

[
  {
    "request": {
      "principal": "User::\"alice\"",
      "action": "Action::\"delete\"",
      "resource": "Document::\"doc1\"",
      "context": {}
    },
    "entities": [
      {
        "uid": {
          "type": "User",
          "id": "alice"
        },
        "attrs": {
          "role": "user"
        },
        "parents": []
      }
    ],
    "decision": "deny",
    "reason": [],
    "num_errors": 0
  }
]

Defining the entities inline becomes inconvenient for large entity sets and when entity sets should be reused between test cases. We should support a syntax like

[
  {
    "request": {
      "principal": "User::\"alice\"",
      "action": "Action::\"delete\"",
      "resource": "Document::\"doc1\"",
      "context": {}
    },
    "entities": "entities.json",
    "decision": "deny",
    "reason": [],
    "num_errors": 0
  }
]
