`layout` config-option: long

not a bug, but a feature request...

$ #- os: 
$ inxi --system | tail -n1
  Desktop: Cinnamon v: 6.0.4 Distro: NixOS 24.05 (Uakari)

$ lsd --version
lsd 1.1.2

$ echo $TERM
xterm-256color

$ echo $LS_COLORS
...

Expected behavior

• the layout config option has some value say "long" to specify long-listing i.e. equivalent to -l or --long cli flag.
• documentation for blocks itself mentions this 😄

Actual behavior

layout only accepts grid, tree, oneline and errors out 3 times at long value.

$ lsd
lsd: Configuration file /home/.../.config/lsd/config.yaml format error, layout: unknown variant `long`, expected one of `grid`, `tree`, `oneline` at line 4 column 9.

Start by tracing the configuration parsing and layout handling for the accepted grid, tree, and oneline values, then review the README sections linked in the issue. Done means long is accepted as a layout value, produces long-listing behavior equivalent to -l or --long, and the relevant documentation reflects it.
