vm-cli reworked.

now accepts -kind and -delay flags.

arg parsing moved into separate run_commands function.

+Toggle with `!` prefix, get by excluding `=` and set by including `=`. Mix and match arguments.
+You may pass an optional flag -kind to set the kind of Voicemeeter. Defaults to banana.
+You may pass an optional flag -delay to set a delay on the getters. Defaults to 15ms.
