microfetch: init at 0.3.3

Addition of [microfetch]:

> A stupidly simple fetch tool, written in Rust. Runs in a fraction of a
> second, displays most nonsense people on r/unixporn care about. Aims
> to replace fastfetch on my system, but probably not on yours. Though
> you are more than welcome to use it on your system: it's fast.
