RFE: also include Service Control Policies

> Service control policies (SCPs) are one type of policy that you can use to manage your organization. SCPs offer central control over the maximum available permissions for all accounts in your organization, allowing you to ensure your accounts stay within your organization’s access control guidelines

该 issue 请求为 iamy（一个用于配置 AWS IAM 的 CLI 工具）添加对 Service Control Policies (SCPs) 的支持。首先检查现有的用于将 IAM 资源导入和导出为 YAML 的代码结构。了解其他 AWS policy 类型的处理方式。研究用于 SCPs 的 AWS Organizations API。确定需要对数据模型、CLI 命令和同步逻辑进行哪些更改。'Done' 表示 iamy 可以从 YAML 文件导入 SCPs，并将 SCPs 导出到 YAML 文件。
