Option to omit empty workspaces on ends from bar unless focused

[zetaPRIME]

I'm not sure if the handling for this would be in the IPC or within the Waybar module, but being able to set things up such that empty workspaces on the ends of the set are only shown if focused would be a great look-and-feel tweak. Bonus points if said mode numbers empty-workspace-above-first as 0 until a window is opened there.

I think it should be implemented in Waybar. It can check if the workspace has no windows.

I've implemented a hacky solution in my waybar css for now, but it's very css-dependent since gtk css doesn't support display: none at all:

#workspaces button.empty:not(.active) { /* hide empty workspaces */
  margin-left: -10px;
  margin-right: -16px;
  padding: 0px;
  color: transparent;
  background-color: transparent;
  border: none;
}

fwiw you might be able to simplify this to just opacity: 0 instead of setting color, background-color and border manually

but that depends on whether or not GTK does that or not
