oximod 0.2.5

//! Delete example for oximod
//!
//! Run with: `cargo run --example delete`
//!
//! This demonstrates how to:
//! - Insert users
//! - Delete multiple documents (raw MongoDB collection)
//! - Delete one document with a filter (raw MongoDB collection)
//! - Delete a document by ID using `Model::delete_by_id`
