How does clipboard manager's writeImage function work?

If i try to write images like the example:

```ts
import { writeImage } from '@tauri-apps/plugin-clipboard-manager';
const buffer = [
// A red pixel
255, 0, 0, 255,

// A green pixel
0, 255, 0, 255,
];
await writeImage(buffer);
```

I get an error on the webview console
`Unhandled Promise Rejection: expected RGBA image data, found raw bytes`

If I try to convert an image to RGBA data in rust then pass the buffer I still get the same error
```rs
#[tauri::command(async)]
#[specta::specta]
pub fn image_path_to_rgba_bytes(path: &str) -> Vec {
let img = image::open(path).unwrap().to_rgba8();
img.into_raw()
}
```

```ts
const rawImage = await commands.imagePathToRgbaBytes(imagePath);
await writeImage(rawImage);
// Unhandled Promise Rejection: expected RGBA image data, found raw bytes
```
