Review Comment:
Thank you Fokko, my understanding is that the problem occurs when the
provided `region` doesn't match the data file bucket region, and that will fail
the file read for pyarrow. And by overwriting the bucket region (fall back to
provided region), we make sure the real bucket region that a data file is
stored takes precedence. (this function is cached when using `fs_by_scheme`, so
it will be called only for new bucket that's not resolved previously to save
calls to S3)
