"hyper-statusline" plugin support

[arcticicestudio]

The hyper-statusline plugin should be supported with optimized style integration.

1. The background should be colorized with nord1
2. The font should be colorized with nord4
3. The Git status indicator icons should be colored with nord13 for the dirty state and nord7 for the modified- and remote-compare state (icon_push and icon_pull CSS classes).
4. The transition should match the tab animation
