Added windows support

[Mohammadsaknini]

Singnal is only partially supported under windows, so i created the timeout function using threads instead of singals which should work on windows as an alternative.

Tbh its been a while, but i do think it is indeed a typo. Probably forgot to remove it while fiddling around with the code.

I've tested the code and it does work on Windows.
There were some further modifications needed on loop.py though, due to a similar timeout construct occuring in it without calling the util.py/timeout function.

Kudos for the fix, it really helped me. Thanks! 👍

Dear @Mohammadsaknini I applied your changes to util.py and still get this Attribute Error: module 'signal' has no attribute 'SIGALRM'. Did you mean: 'SIGABRT'? whenever I want to test the examples against Popper. I would be thankful for your help!

This pull request was created a year ago, and I'm not sure if the codebase is still the same. However, according to Peterasa, there appears to be a similar timeout construct in loop.py, so it might be worth checking that.
