Features:
- *Backwards-incompatible*: Modify ``alt_response`` signature. The second
positional is now a response reference as string. If none is provided, then
the response dic is built using keyword arguments. The schema is optional and
can be a reference as string. (:pr:`283`)
- Allow ``alt_response`` to define a success response, so that other
processings applying to this response are correctly documented (:pr:`284`).
Other changes:
- Format code using black with pre-commit (:pr:`282`).
- Use dependabot to update dependencies (:pr:`286` and :pr:`288`).
- Specify `apispec[marshmallow]` rather than `apispec` in `install_requires`
in setup.py (:pr:`287`).
