Mypy support

[samupl]

Hey,

Would it be possible to have type hints for this library? Currently when using this library in my project where I wanted to add static type checks, mypy complains:

error: Skipping analyzing "rest_framework_json_api.relations": module is installed, but missing library stubs or py.typed marker [import] note: See https://mypy.readthedocs.io/en/stable/running_mypy.html#missing-imports 

Is that something this library would be interested in supporting?

Thanks for raising this discussion.

Having mypy support could be something useful for DJA. However, as outlined in our 3rd party policy we want to avoid adding too many features to DJA directly. Secondly Django REST framework also seems to have its mypy support in an external library.

Therefore, I would prefer seeing such a stubs support in a separate library as well. If anyone is willing to work on this, best to create a repository and raise it here so other people who are interested can join in the effort as well.
