文字轉影片
透過 CometAPI 使用 Runway 的 POST /runway/pro/generate 產生 GEN-4 文字轉影片，並支援以 X-Runway-Version 進行版本化輸出。

}CometAPI 上的必要欄位
callback_url目前為此封裝器必填prompt、ratio、style與model用於定義生成請求options.seconds與options.motion_vector為目前封裝器 schema 的必填欄位
已驗證的請求路徑
- Header：
X-Runway-Version: 2024-11-06 - Model：
gen4_turbo - 回應：
code: 200、msg: 成功，以及data.task_id
