Performance compared to Image

## 🏗 Performance issue

I have performance issues with using this package in a list.

```
CachedNetworkImage(
imageUrl: _imageUrl,
fit: BoxFit.fitWidth,
height: 40,
width: 40,
errorWidget: (context, url, error) =>
const SizedBox(width: 40, height: 40, child: AppLogo(40, 40)),
placeholder: (context, url) => const SizedBox(width: 40, height: 40),
)
```

Sadly this results in pretty high **raster ms/frame, about** **40-80 even without scrolling.**
If I'm using Image or FadeInImage.memoryNetwork, I'm getting raster **ms/frame about 9-11** and lower around **7ms UI thread**.

```
FadeInImage.memoryNetwork(
image: _imageUrl,
fit: BoxFit.fitWidth,
placeholder: kTransparentImage,
placeholderErrorBuilder: (_, __, ___) => const SizedBox(
width: 40,
height: 40,
child: AppLogo(
40,
40,
useSmallImage: true,
),
),
)
```

Is there any option to improve this? It's laggy on the first time and even after caching the images its not comparable.
