feat: implement custom keyboard shortcuts

This feature was requested in

https://github.com/ayushnix/tessen/issues/30

and

https://github.com/ayushnix/tessen/issues/32

This feature is inspired from rofi-pass. However, rofi-pass implemented
this feature only for rofi by using its command line flags. Since tessen
intends to work with multiple dmenu scripts, I've mapped the actions to
exit codes instead. This would allow users to map exit codes greater
than 10 to whatever keybindings they prefer.
