Incorrect ordering of CPU Core names.

[mkrasnitski]

CPU Core names are listed in pure alphabetical order, with CPU10 and CPU11 being listed before CPU2. It'd be better to list them using a more natural sort. Afaik this is a new issue in v4.1.0, it is not present in v4.0.1. Here's an image:

gotop version:

gotop v4.1.0 (20210125T182337)

OS/Arch:

Arch Linux/5.10.10-zen1-1-zen

Terminal emulator:

I don't believe there were any changes that would have caused this; if you get a chance to download v4.0.1 (from the releases page) and try it, I'd be interested to see whether there's a difference. I don't have more than 8 cores so I can't see myself. In any case, whether it's a regression or not, it's ugly the way it is so we'll get it fixed.
