Possible to add support for types?

I have been enjoying using get_object_or_None all over my project in place of lazy incorrect .first() calls, and it's really great. However, it has the downside of losing the information about the object's type. Pyright tells me the returned type is Unknown | None, even though I know it has to be the corresponding type of the Model | QuerySet | BaseManager that I passed as klass.

Types are definitely something that need to be added, any contributing PRs are welcome!
