Feature Request: Allow running tool on MacOS and other Linux distributions

[serid]

Describe Your feature request:
Cache querying system is currently non-portable.

iFunny-Captions/__init__.pyw

Lines 77 to 79 in 3387e47

	if not system() == "Windows":
	import apt
	cache = apt.Cache()

This block of code works on Windows and Debian/Ubuntu, but fails on any other OS, for example MacOS and Arch Linux.
Here is a docker file reproducing the error "ModuleNotFoundError: No module named 'apt'":

https://pastebin.com/E4X7F1x4

Make sure to run the image several times since sometimes the tool flukes and does not report error.

Why should I add that?:

This would allow running the tool on MacOS and linux distributions other than Debian derivatives like Ubuntu.

I admit that this will be very hard to fix, since there is no - as far as I know - built-in cross-platform package for Python that provides support for system installed packages.
