Attach sway workspace to a display

The config code is:

# Current displays are: 
# 1) HDMI-A-4 
# 2) DVI-D-1
# 3) VGA-1

	workspace F13 output HDMI-A-4 
	workspace F14 output HDMI-A-4 
	workspace F15 output HDMI-A-4 
	
	workspace 0 output DVI-D-1
    ...
	workspace 10 output DVI-D-1

	workspace browser output DVI-D-1
	workspace F1 output DVI-D-1
	workspace F2 output DVI-D-1

	workspace F16 output VGA-1
	workspace F17 output VGA-1
	workspace F18 output VGA-1
	workspace F19 output VGA-1

That’s how I did that on farm.

If I want to attach workspace to multiple outputs, I need to specify it multiple times:

	workspace 0 output DP-1
        ...
	workspace 9 output DP-1

	workspace browser output DP-1
	workspace mail output DP-1
	workspace viber output DP-1
	workspace telegram output DP-1
	workspace files output DP-1
	workspace gimp output DP-1
	workspace code output DP-1


	workspace 0 output HDMI-A-1
        ...
	workspace 9 output HDMI-A-1

	workspace browser output HDMI-A-1
	workspace mail output HDMI-A-1
	workspace viber output HDMI-A-1
	workspace telegram output HDMI-A-1
	workspace files output HDMI-A-1
	workspace gimp output HDMI-A-1
	workspace code output HDMI-A-1
