Struct SeriesGroupByExpanding 

pub struct SeriesGroupByExpanding<'grouped, 'data> { /* private fields */ }

Grouped expanding window over a SeriesGroupBy.

Created by SeriesGroupBy::expanding(). Applies existing Series expanding operations within each group independently, then maps the results back to the original flat Series index.
