ext-workspace support

[ToxicMushroom]

Is your feature request related to a problem? Please describe.
Currently the supported compositors for workspace module is very limited and requires compositor specific implementations.
This is a newly merged wayland protocol for workspaces that aims to unify this process

Describe the solution you'd like
Use this protocol in the workspace module.
Ironbar can then hopefully be used to show workspaces on any comp that implements this protocol :)

I think sway already does since it was based on their wlr workspace thing but not sure.

Describe alternatives you've considered

I'd like to see both of Sway and Hyprland support the protocol first, as those are the two with merged support for the module. Once they ship releases, I'll definitely be happy to move away from relying on their IPCs

Niri will be implementing ext-workspace in niri-wm/niri#1800.

Hyprland has merged support

[Brisingr05]

Niri has also merged support: niri-wm/niri#135 (comment)

this is the only reason why i do not use ironbar on mangowc. mangowc just merged support.
