Compiling configuration does not work

[yamaguchi1024]

How to reproduce: put the following code in tmp.py and run exocc on it.

from __future__ import annotations
from exo import proc, config

@config
class Test:
    a: f32 

@proc
def foo(x: f32):
    Test.a = 32.0
    x = Test.a

print(foo)  

$ exocc tmp.py
Traceback (most recent call last):

The problem is that cls in parse_config does not have __file__ attribute, and this seems like a known issue in Python ( https://bugs.python.org/issue12920 )
