FR: recursive delete should have a callback with document data

**Is your feature request related to a problem? Please describe.**

Yes, I want to perform a recursive delete and need the data of the deleted documents to perform subsequent operations to clean up my database.

**Describe the solution you'd like**

RecursiveDelete creates a stream reading all documents that are being deleted => so if we are reading the data anyway why not pass them to a callback function?

**Describe alternatives you've considered**

Add an onDeleteDocument listener to every document. I am not a fan of this approach because I prefer to keep data logic in a single function. It is also not a clean approach because it leads to cases where onDelete is triggered unnecessarily.

**Additional context**
I could create a pull request if you want
