GEPRC KX5 GoPro Session Mount

GoPro Mount for the GEPRC KX5 Frame.
It has been derived from Lefty9's GroPro mount for the Chaemeleon (ID 2747042). I really like Lefty's design, so I changed the part that adapts to the frame.
The GoPro session mount itself is unchanged. The lower strap holder is changed to fit into the KX5 frame and allows the slim strap delivered with the frame to secure the holder. The strap can go through the aluminium slots and pass trough the mount's strap holder this way.
