Current Magic Trackpad is familyID 129, not 130

The current iteration of the Magic Trackpad 2 (large corners, matching the Magic Keyboard with the Lock button in the top right corner) is still reporting as 129 and not 130, as assumed in the code.

I think the code does expect the Magic Trackpad 2 to have Family ID 129, and 130 is a placeholder for a future Magic Trackpad 3 (which may or may not happen, similar to 113 being assigned to a built-in trackpad instead of the next Magic Mouse).
