Wing Wing Z-84 - Top part - GoPro Session

I've attempted to add a GoPro Session mount to the orginal Wing Wing Z-84 - Top part by yannoch.

The idea is based on the fact that wing wings love to fly with a bit of extra heft. Nothing does that better than a GoPro. Oh, and because GoPro.

-This is V1! I have not made this part yet. Feedback is welcome.
-Now better with V2!!!!. Added a cutout that should make the cover fit wings with 4cell 18650 packs.
-Added V3. Now fits GoPro session better.
-V4. Small bug fixes and improvements.
