I think from the `Vec<Expr>` could not mapping back to the only unique
`Vec<Vec<Expr>>` and hence unparse the cube statement would be difficult. How
about store another copy of origin Vec in the Cube and Rollup instance? i.e.,
```rs
pub enum GroupingSet {
/// Rollup grouping sets
Rollup(Vec<Expr>, Vec<Vec<Expr>>),
/// Cube grouping sets
Cube(Vec<Expr>, Vec<Vec<Expr>>),
/// User-defined grouping sets
GroupingSets(Vec<Vec<Expr>>),
}
```
