Review Comment:
The first check in `openVectorized` is this:
```
Preconditions.checkArgument(!task.file().format().equals(FileFormat.AVRO),
"Vectorized execution is not yet supported for Iceberg avro
tables. " +
"Please turn off vectorization and retry the query.");
```

> With vectorized Iceberg reads we are creating {{HadoopInputFile}} objects
> just to store the location of the files. If we can avoid this, then we can
> improve the performance, since the {{path.getFileSystem(conf)}} calls can
> become costly, especially for S3
