New models of Nix and Hydra

[Shadow-Dragon-777]

Couple months ago, I found models of Nix and Hydra. SevenSpheres converted them to CMOD.
The models replace the Hydra one and add a Nix one. They are based on scientific studies of them as seen in the readme. Currently there is no way to align these correctly as both of them tumble "IE Do not have permanent axial poles" because of gravitational torques caused by the Pluto Charon binary itself. Unfortunately, no scientific maps of these two exist yet so you will have to look for amateur made maps to fit on them.

for hydra, if you take the CO code for it, and remove the orientation block (done that in code below), that will put the model at the correct orientation, can't say the same fir nix though sadly

and here is a Nix and Hydra map i reprojected using these models

a map of Nix from Askaniy is in the works right now, can't wait for askaniy to stitch together the images and color this john

Askaniy got done a grey-scale map of Nix
