Add option to save layouts similarly to what i3wm allows you to do it

[Lukibukiboy]

When doing development I often have the same four or more windows open, in the same layout. It would be useful to be able to save a session and quickly restore any required layout for a given task or set of tasks. Obviously this can be hacked together via scripts, but it does seem like natural extension of functionality for a tiling compositor that handles window layout.
P.S: Thank you for your excellent work so far. Hyprland on wayland is terrific :-)
