Add supper for person/vehicle detection on G4 Instant.
**Describe The Problem:**
With the latest protect app (2.1.1), the G4 instant has received person and vehicle (aka smart detection) capability. It would be great to have the instant also add the contact sensors like other G4 series cameras provide for person/motion detection.

**To Reproduce:**
Use a G4 Instant with latest protect app and notice that the plug-in doesn't expose person/vehicle contact sensors.
