Method to_owned

rustcv-camera/src/frame.rs:165–174

Copy the raw data into an [`OwnedFrame`] that can outlive the camera borrow. 将原始数据拷贝到 [`OwnedFrame`]，使其可以超出摄像头的借用生命周期。 Use this when you need to: - Send frame data to another thread - Keep frame data after calling `next_frame()` again - Store frames in a collection 在以下场景使用： - 将帧数据发送到另一个线程 - 在再次调用 `next_frame()` 后仍保留帧数据 - 将帧存储到集合中
