Is there any plan to support window aggregation in Calcite Query Engine

```
select "deptno",
rank() over (order by "deptno") as r
from "hr"."emps"
```
Calcite supports the above Sql, but Ignite's Calcite Query Engine does not support window aggregation syntax. Is there any plan to implement window aggregation in Calcite Query Engine.

No file or test is named. Begin by tracing how the Calcite Query Engine handles the shown rank() OVER (ORDER BY "deptno") query, then define support and verification using the hr.emps example. Done means the query executes successfully in Ignite's Calcite Query Engine.
