cc @alamb , what do you think about this, this can remove the `each row group row selection` -> `full row selection` -> `each row group row selection` convert, but for e2e performance it do not imporve in normal query i think. but it have two bennefit for the user that already have a `RowSelection`. 1. user able to choose `bitamp` or `rowselecter` represention in row_group level, current only support file level 2. it can improve some performance when user have a fragmented rowselector(the case describe in https://github.com/apache/arrow-rs/issues/10140#issuecomment-4726551760). -- This is an automated message from the Apache Git Service.
