Add zoom to SimConnect_CameraSetRelative6DOF()

Please add camera zoom parameter to SimConnect_CameraSetRelative6DOF().

I'm struggling to find a way of setting the zoom level with SimConnect so I can cut my dependency on FSUIPC.

I also need the ability for camera settings to be ignored or actioned depending on the type of view the user currently has in focus. i.e. How about adding another parameter that takes an enum like VC_ONLY, or VCONLY|2D_ONLY, or VIEW_ALL.
