Create virtual monitor for testing multi-monitors.

Options:
  -h, --help       Show this help message and exit
  -c, --clean      Clean all tester monitors and wayvnc sessions and exit
  -d, --daemon     Run in background
      --no-guard   Disable hypr_mon_guard. Tip: this process can
                   also be terminated using ${STY_BOLD}pkill hypr_mon_guard${STY_RST}

For the syntax of following options, see also Hyprland Wiki:
  https://wiki.hypr.land/Configuring/Monitors
      --res <res>  Resolution, by default ${STY_UNDERLINE}$VMON_RESOLUTION${STY_RST}
      --fps <fps>  Refresh rate and FPS, by default ${STY_UNDERLINE}$VMON_FPS${STY_RST}
      --pos <pos>  Position, by default ${STY_UNDERLINE}$VMON_POSITION${STY_RST}
                   Examples: ${STY_UNDERLINE}auto-left${STY_RST}, ${STY_UNDERLINE}0x-1080${STY_RST}
      --sca <sca>  Scale, by default ${STY_UNDERLINE}$VMON_SCALE${STY_RST}
      --ext <ext>  Extra properties, e.g. ${STY_UNDERLINE}transform, 1${STY_RST}

Note 1:
  The virtual monitor will be served via wayvnc.
  You need a VNC client to connect to it.
  Recommended VNC client:
  - Android: AVNC (https://github.com/gujjwal00/avnc)
  - Linux X11, Windows and MacOS: TigerVNC (https://github.com/TigerVNC/tigervnc)
  - Linux Wayland: Remmina-VNC (https://remmina.org/remmina-vnc)

Note 2:
  You can run this subcommand multiple times to create multiple virtual monitor. To do this, use ${STY_UNDERLINE}-d${STY_RST} to run wayvnc in background and repeat again, or just open extra terminal/shell and run the subcommand again.

Note 3:
  If you do not have a spare device connected to the same network, it's still possible to test multi-monitor by using VNC client on this device, in which case the <IP> should be ${STY_UNDERLINE}localhost${STY_RST} or ${STY_UNDERLINE}127.0.0.1${STY_RST}.
