Resolution (macOS): improve detection

Browse source 
1. fix detection when `screenresolution` is not available
2. make scale factor detection actually work
3. remove `screenresolution` dependency

EDIT: applied changes suggested by @hykilpikonna and fixed a
[bug](https://github.com/hykilpikonna/hyfetch/issues/196) that neofetch
fails to print scale factors when `system_profiler` fails to detect
refresh rates.
