Allow typing and still trigger by hash and eq

An experiment, might work. The idea is to make FakeModule hashable only if typing module is in the call stack.

Perhaps something like inspect.getmodule(frame) and something from frame.f_globals to prevent false positive from a random package having a typing.py file

[Mandera]

Ohh!! Can just do

from inspect import getmodule
import typing

...
if getmodule(frame) is typing:
