Will recursively flatten messages of a node and all its children.
This helper can for instance be used when errors occurred during a
mapping to flatten all caught errors into a basic array of string that
can then easily be used to inform the user of what is wrong.
```
try {
// …
} catch(MappingError $error) {
$messages = (new MessagesFlattener($error->node()))->errors();
foreach ($messages as $message) {
echo $message;
}
}
```
