Cleanup: Fix Mypy errors in init1.py

[hoh]

The only Mypy error left is related to the use of the type ASGIApplication, defined as:

ASGIApplication = NewType("ASGIApplication", Any)

init1.py:46: error: Argument 2 to NewType(...) must be subclassable (got "Any")  [valid-newtype]

I did not find any easy solution for that. It does not seem blocking.

Can't you just replace Line 35 with

ASGIApplication = Any

in this case? Reading up on NewType, you are not loosing anything important anyways in terms of type safetly, when subclassing Any.

And also, can you add the debian runtime to the paths to be checked by mypy and others in the GH action?
