on file version of the V2 unfolder

[gilboonet]

Hello, I made a mono-file version of my V2 Unfolder, so that it can be used by simply clicking of this link : https://openjscad.xyz/#https://raw.githubusercontent.com/gilboonet/gilboonet.github.io/master/outils/unfolderV2Flaps/deplieur_cadhub.js

I added lots of models on it by opening them into JSCAD then saving as JSON, opening this JSON, copy-paste it into my script, and it works nicely.

The big drawback is that this version is not able to unfold a new file, for that the only way is a local project where the file is copied.
