The screenshot feature no longer requires any configuration before working. We no longer hardcode `${HOME}/Pictures/neofetch` as the screenshot location. Here's how the `-s` and `-su` flags now function:
-`neofetch -s` will save a file in the current directory named: `neofetch-$(date +%F-%I-%M-%S-${RANDOM}).png`
-`neofetch -s test.png` will save a file in the current directory called `test.png`
-`neofetch -s ~/` will save a file in `~` called `neofetch-$(date +%F-%I-%M-%S-${RANDOM}).png`
-`neofetch -s ~/test.png` will save a file in `~` called `test.png`.
