Combo binds

Especially for controller, it would be nice to set keybinds on key combos

Deciding not to do this, it's rather complex with a number of difficult questions we'd have to answer:

• The standard unreal key event system, which we hook in both oak and willow, doesn't deal with modifiers at all, we only get one key event at a time. Oak does seem to have PC.WasInputKeyJustPressed, but in willow we'd need to add statefullness, which could easily get out of sync.
• We don't want pressing a combo to trigger the keybinds of it's individual keys, so we'd need to block them, but there will always be a short duration on either side where only one key is pressed. When do we block key inputs?
• If we support 2 button combos, can we do 3 or more? Especially on controller which doesn't have many free keys.
• If we have combos, can we have layering?
• How would the UI of any of this work in the mod menus?

Rather than work this all out ourselves, Steam Input already solves basically all of this. The recommended solution is to setup your layers/chords in Steam Input (or really any rebinding program), and bind them to some unused key.
