JoyToKey timed press

[paoloambrosio]

• Support short or long key presses (example from ACC)

Example configuration and expected behaviour:

usb_input:
- device: Fanatec CSL Elite
  rules:
  - controls:
    - Button 4
    events:
    - name: flasher
    - min_press_ms: 500
      name: toggle_lights

• If TimeReleased-TimePressed < 500ms (the button is released within 500ms), send KeyDown and KeyUp at TimeReleased.
• Otherwise, send KeyDown at TimePressed+500ms, send KeyUp at TimeReleased.
• Note: as timestamp for the event KeyDown always uses TimePressed and KeyUp uses TimeReleased, no matter when they are generated.

We should be able to support delays for multiple button combinations (to avoid generating events for the single buttons being pressed):

usb_input:
- device: Fanatec CSL Elite
  rules:
  - controls:
    - Button 1
    - Button 2
    events:
    - name: together
  - controls:
    - Button 1
    events:
    - min_press_ms: 50
      name: one
  - controls:
    - Button 2
    events:
    - min_press_ms: 50
      name: two
