Support for new typeguard version

[albertz]

Currently you pin to an old typeguard version. This is a problem for me, because I want to use it together with some other code which requires a newer typeguard version.

As I understand #5009, just no-one so far has invested some effort in updating the code? But in principle, you are ok with updating the code?

As I understand it, instead of using check_argument_types() and check_return_type(), use the @typechecked decorator on the function.

Note, I also asked whether we can maybe get back check_argument_types() and check_return_type() in newer versions of typeguard, but I doubt that they would add it back. agronholm/typeguard#437

Thanks, @albertz.

@kamo-naoyuki, can you answer it?

@albertz Yes. It's great if you'll update.
