List monitors command should be more descriptive

[haxybaxy]

I would really love it if the aerospace list-monitors command would show you which display is the main display, rather than just the number and name.

I'm currently using aerospace with sketchybar, and I am using the aerospace list-monitors command in order to be able to get my bars to align with the proper monitor.

I move set ups frequently, and my main display changes frequently based on where I am at, which means I always have to mess with my config when going from home to the office etc. since I use my laptop as the main screen at home, while I use an external screen as the main one in the office.

The numbering of the screens for the list monitors command starts from left to right, so its highly dependent on where my laptop is placed and it makes me have to align my monitors in an uncomfortable way in order for things to work properly.

We can already use 'main' and 'secondary' in the config, can't we also have the command include a flag that says whether the display is the main one or not? Thank you
