isd: 0.2.0 -> 0.5.1

- `kmonad` is now hardened by default using common `systemd` settings.

  If KMonad is used to execute shell commands, hardening may make some of them fail.  In that case, you can disable hardening using {option}`services.kmonad.keyboards.<name>.enableHardening` option.

- `isd` was updated from 0.2.0 to 0.5.1, the new version may crash with a previously generated config, try moving or deleting `~/.config/isd/schema.json`.

- `asusd` has been upgraded to version 6 which supports multiple aura devices. To account for this, the single `auraConfig` configuration option has been replaced with `auraConfigs` which is an attribute set of config options per each device. The config files may also be now specified as either source files or text strings; to account for this you will need to specify that `text` is used for your existing configs, e.g.:

  ```diff

  -services.asusd.asusdConfig = '''file contents'''
