Description

### Task Description

Currently, column stats and partition stats are not supported with Lance file format. Such support needs to be added.

Particularly, `LanceUtils` does not implement reading column stats metadata from the Lance files.

```
@Override
public List> readColumnStatsFromMetadata(HoodieStorage storage,
StoragePath filePath,
List columnList,
HoodieIndexVersion indexVersion) {
throw new UnsupportedOperationException("readColumnStatsFromMetadata is not yet supported for Lance format");
}
```
