> During the migration of CSV V2, I find that we can improve the file source v2 framework by:
> 1. check duplicated column names in both read and write
> 2. Not all the file sources support filter push down. So remove `SupportsPushDownFilters` from FileScanBuilder
> 3. The method `isSplitable` might require data source options. Add a new member `options` to FileScan.
