### Describe the bug, including details regarding any error messages,
version, and platform.
When trying to use `MessageColumnIO` to get a record reader, the following
error occurs:
```
Exception in thread "main" java.lang.UnsupportedOperationException

I expected that this would work. Pyarrow for example can read the file.
