Groupings for sway and dynamically build waybar sections

[bschnitz]

Hi,

I just created a CFFI module, which allows to dynamically populate part of the waybar, d.i. use ipc to change the waybar contents and style classes without the necessity of restarting waybar. I named it waybar-dynamic and I already feel sorry for such a lack of creativity when choosing a name.

However this was just a prerequisite for another project, which allows to create groups of workspaces in sway, which has an equally creative name: sway-groups. I needed to solve the problem of having too many workspaces for too many projects open at once, so grouping them was the natural solution for me. Also it has some other features, like hiding workspaces (from certain groups) - very useful for presentations - or workspaces which are shown on all groups.

The coding was done mainly using ai, which an honourable software engineer would never use, but fortunatly I don't have that much honour any more.

I never installed it fresh on any other device, so I hope the installation instructions are sufficiently accurate. But if not, or if You find any other bugs, feel welcome to open an issue.

Have Fun! (Hopefully.)
