Generic ExcelWriter

[9en9i]

I noticed that the annotations for the ExcelWriter class differ from those in the main pandas repository. The latter uses a generic type, which simplifies code writing. Could you please tell me whether the rejection of the generic type is intentional?

Changes made to the pandas source that are for typing are not always known to us in pandas-stubs. So if someone does a PR for pandas that improves the typing for pandas (which is intended to help pandas developers), we don't always track those as potential changes to make to pandas-stubs (which is intended for pandas users).

Having said that, we are open to PR's that align things better.

Thank you for your reply. I will try to open a PR as soon as possible.

I opened PR #1561. Added a generic for ExcelWriter, as well as an overload for the constructor.
