Refactoring and fix for #14 (AMD issue)

[Red-Eyed]

• A bit of refactoring
• solves KeyError: 'coretemp' #14 As I didn't find how to get temperature for AMD Ryzen, I just display acpitz instead of core temp.

This is great, thank you for your contribution!

Since it seems you have an AMD CPU and know your way around it. If you have time to look at #17 that would be great. As resolving this would basically add AMD support for auto-cpufreq which would be a huge contribution.

Yeah, I read about #17. But in my case , I have 2 governors: performance and powersafe.
It seems that some AMD CPUs don't have powersafe but schedutil instead.

BTW: I increased my bat life from 5h to 9h! it's very nice and helpful project, thank you for this!
Also, it's cool that it's written in python, because I'm a python dev and very love thins language, so glad to contribute :)

Weird, first thing that comes to mind is to make additional check which governors to use based on which AMD CPU is detected.

Most welcome, thank you as it's always great to hear feedback like this :)

Great! In that case I hope I'll see more of your pull requests and I'll make sure to add your contributions in release notes of a new release.
