feat: -Z SELinux context support

[boredsquirrel]

when using ls on Fedora, CentOS, RHEL, AlmaLinux etc, there is an additional argument -Z to display SELinux contexts.

Can look like this

/ ❯❯❯ ls -Z
       system_u:object_r:bin_t:s0 bin@          system_u:object_r:lib_t:s0 lib64@         system_u:object_r:proc_t:s0 proc/        system_u:object_r:root_t:s0 sysroot/
      system_u:object_r:boot_t:s0 boot/         system_u:object_r:mnt_t:s0 media@   system_u:object_r:admin_home_t:s0 root@         system_u:object_r:tmp_t:s0 tmp/
    system_u:object_r:device_t:s0 dev/          system_u:object_r:mnt_t:s0 mnt@        system_u:object_r:var_run_t:s0 run/          system_u:object_r:usr_t:s0 usr/
       system_u:object_r:etc_t:s0 etc/      system_u:object_r:default_t:s0 nix/            system_u:object_r:bin_t:s0 sbin@         system_u:object_r:var_t:s0 var/
 system_u:object_r:home_root_t:s0 home@         system_u:object_r:usr_t:s0 opt@            system_u:object_r:var_t:s0 srv@
       system_u:object_r:lib_t:s0 lib@          system_u:object_r:usr_t:s0 ostree@       system_u:object_r:sysfs_t:s0 sys/

This is currently the only thing keeping me with ls
