Regarding the filter for methods like `update_one()`, etc, allow users to directly use `ObjectId()` as filter

Usually it is used like:

db.collection.update_one({'_id': ObjectId('6ef...d32')}, ...) 

Proposed: To allow API usage like this:

db.collection.update_one(ObjectId('6ef...d32'), ...)

Also, the method `find_one()` allows for this style
