[FEAT]: Ability to pause/resume whkd

[freijon]

Is your feature request related to a problem? Please describe.
Some programs use the same hotkeys than what I've bound with whkd, for example Alt+Return in MS Excel. These app-specific hotkeys no longer work with whkd running.

Describe the solution you'd like
It would be nice to be able to have an internal "pause" command. Once toggled on, it would ignore all future key binds (basically a passthrough mode) until the command is toggled off. This would allow us to pause whkd selectively and resume operation.

Describe alternatives you've considered
I created this keybind as a workaround:
alt + control + o : taskkill /f /im whkd.exe; sleep 10; Start-Process whkd -WindowStyle hidden
It kills whkd, waits for 10 seconds and restarts it again. But that's not optimal.
