Wrong types of TagRunnerOptions.args

Environment

• Version:

  cli version: 0.3.0
  core version: 0.2.1
  build version: 0.2.1
  serve version: 0.2.1
  

What's wrong?

The args property of TagRunnerOptions was constianted to be string, number, or boolean.

export declare type TagExtensionArgTypes = string | number | boolean;
export interface TagRunnerOptions {
    context: nunjucks.Context;
    args: TagExtensionArgTypes[];
    contentArgs: TagExtensionContentArgGetter[];
    metadata: NunjucksExecutionMetadata;
}

But it can be object if inputs are keyword arguments.

{% tagname foo="bar" %}

What's the correct behavior?

It should be allowed to be Record too.
