Review Comment:
@Fokko thanks for the review.
I agree with the above. The Arrow FileIO implementation might not be the
best place to implement this behavior. So far both of the supported FS
implementations (`ARROW_FILE_IO` and `FSSPEC_FILE_IO`) are failing to write to
the local file system.
I want to make writes work for the local file system.
Looking at the Java side, there is a [`LocalOutputFile`
implementation](https://github.com/apache/iceberg/blob/fd1cf49280bde07d67c6bc1a6ec60238e1e38f7f/api/src/main/java/org/apache/iceberg/Files.java#L59)
which implements the behavior for creating parent directories.
Maybe we can implement a new FileIO implementation and make that the
preferred implementation for the `file://` scheme.
