I see, I didn't account for that It will require so large rework. Sure such
approach with passing extension_meta through PartitionedFile will work for me,
but could we allow different types of MetadataExt ? Like in example below. That
would allow me to simply reinterpret pointer behind box, without having to
parse components.
```
pub enum MetadataExt {
Array(Box<[u8]>),
Map(Map<String, String>)
}
extension_meta: MetadataExt
```
