Maybe add ExtensionType to Arrow's DataType is more naturely:
```rust
trait ExtensionType {
fn inner_type(&self) -> &DataType;
// ....
}
enum DataType {
Int8,
Utf8,
// ....
Extension(Arc<dyn ExtensionType>)
}
impl DataType {
fn raw_type(&self) -> &DataType {
let mut ty = self;
while let Self::Extension(ext) = ty {
ty = ext.inner_type();
}
ty
}
}
```
