Polars equivalent of pandas.ExcelDataset

[wolthom]

Description

For pandas dataframes, a specific output dataset for Excel files is supported (Documentation https://docs.kedro.org/projects/kedro-datasets/en/kedro-datasets-6.0.0/api/kedro_datasets.pandas.ExcelDataset.html)
One very appealing feature is the ability to pass in a dictionary of dataframes and generate a multi-worksheet output file.

Context

For the kedro pipelines I am implementing at work, I often implement debug nodes alongside the production pipelines.
Said debug nodes typically output Excel files or visualizations so they are easy to review and interactively browse.
It's extremely useful to be able to create various pre-aggregations, filtrations etc. and output them all in one spreadsheet I can share e.g. with Stakeholders.

Possible Implementation

I don't know the kedro / kedro-datasets architecture well enough yet to propose an implementation strategy.

Possible Alternatives

My current workaround is to simply do my implementations in polars, but transform to pandas dataframes for the output.
While not a huge issue, I would like to keep my dependency tree as small as possible and do not actually use pandas anymore.
