Add signature for ViewAngle/Position from engine2.dll: `dwEngineViewData`

[cycript]

Camera Position and Angles (not ClientViewAngles) are contiguous. (Vec3,Vec3) Struct that I use:

typedef struct EngineCamera
{
    Vector3 Position;
    Vector3 Rotation;
};

I have been using this for a while now, the signature seems stable. Sorry for the bad formatting within the signature string.

Looks good to me, I wasn't aware that it was under CSoundService.

Would you be able to make that change and fix the conflicts so that I can merge this?

I am closing this PR and will just make a new one because its more convenient than solving the conflicts
