**Is your feature request related to a problem or challenge? Please describe what you are trying to do.**
[Window functions](https://www.postgresql.org/docs/current/functions-window.html) are very important in SQL. It enables more complex query to be written, thus more insight can be extracted.
**Describe the solution you'd like**
Substrait window function support.
**Describe alternatives you've considered**
N/A
**Additional context**
DataFusion implements a window function using a `Window` relation and `WindowFunction` expression. However, Substrait only support `WindowFunction` expressions. Thus, the translation is not direct.
