All checks were successful
continuous-integration/drone/push Build is passing
feat: use nnn and treesitter
vifm is removed in favour of nnn, with the keybindings in nvim being
changed. TODO: improve the colorscheme of `nnn` to match `ls`.

All nvim plugins that were responsible for language syntax highlighting
are removed in favour of treesitter[1], a syntax highlighter that parses
AST instead of being regex-based. This is still experimental, but my
tests so far have not encountered any issues.
