Initial support for Hyprland 0.42

This release brings initial support for Hyprland 0.42, since at least one command (e.g.: Clients()) broke in the previous release.

Keep in mind that the support is initial though: I didn't go through the Hyprland 0.42 changelog yet to see if there is any missing commands. Open an issue if you want some specific missing command to be implemented.
