python >=3.11 inspect changes

ignore the extra params in getfullargspec. This is backwards compatible to <=3.10

Since we're dropping support for Python 2 (and your unpacking solution requires 3+ anyway), there's no need to attempt the import of getargspec(). I think we should just import getfullargspec() and use it directly.

[Max-Herbold]

maybe it's more verbose to breakout FullArgSpec(args, varargs, varkw, defaults, kwonlyargs, kwonlydefaults, annotations) to args, varargs, varkw, defaults, kwonlyargs, kwonlydefaults, annotations rather than args, varargs, varkw, defaults, *_.
