Add idle-inhibit

Sometimes I don't want the computer to go to sleep bacause I'm
running something in the background. for that I always used
systemd-inhibit sleep 999999 manually on the terminal, but I want
it to be easy to use without remembering the whole command every
time.

Therefor I added a custom button to waybar which does that for me.
