`types.GeneratorType` is not compatible with the generator type of Cython. This leads to `_run_get_new_deps()` returning directly when the task is from a cythonized module and [yields dynamic dependencies](https://luigi.readthedocs.io/en/stable/tasks.html?highlight=yield#dynamic-dependencies).

Description
types.GeneratorTypeis not compatible with the generator type of Cython. This leads to_run_get_new_deps()returning directly when the task is from a cythonized module and yields dynamic dependencies.Motivation and Context
We have cythonized modules with luigi tasks and noticed that the tasks immediately switch to DONE without doing anything, without logging any error or having any task output.
Have you tested this? If so, how?
I successfully ran cythonized and non-cythonized tasks with this patch.
Side note: I originally wanted to use
typing.Generator, but this now deprecated.There were also no other uses of
typesin the code base.
