Crashlytics fatal error: Connection reset by peer

## 🐛 Bug Report
Firstly, thank you for the wonderful package
Secondly, my problem)

We are using CacheNetworkImage in our application and recently we had several Crashlytics crashes with description "
Connection reset by peer". It is look like this issue https://github.com/flutter/flutter/issues/112706.

The application has screen with list of products and screen with detail information about product. Both of screens use CacheNetworkImage. I don't know why but fatal error occurs on detail screen and have tried to reproduce the crash but i wouldn't be lucky. I can guess that it happens because MultiImageStreamCompleter doesn't cancel a subscription ``
codec.listen((event)
``. Possibly the error occurs when the subscription is still alive but _listeners is empty. In this case MultiImageStreamCompleter can't handle an exception in `reportError` function:
```
if (!handled) {
FlutterError.reportError(_currentError!);
}
```
May be need to call `cancel` method in __maybeDispose for the subscription? Like it is done with _chunkSubscription?
