feat(compositors)!: Add niri
According to its github page, niri is "A scrollable-tiling Wayland
compositor". Myself and coded have been looking for alternatives to
hyprland for stability and community reasons, and niri looks reasonable
for us
It's possible we'll remove hyprland altogether. If we do, we plan to
still maintain a more traditional compositor (e.g. swayfx)
BREAKING-CHANGE: This patch renames some hyprland options
