record: fix multi-monitor and moving across filesystems (#38)

* fix(record): support differing filesystems for recording destination

* fix(record): for multi-monitor-systems wl-screenrec needs a -o argument

* fix(record): replace path.rename with shutil.move

* fix(record): use json option to retrieve hyprland focused monitor

* use generator
