Fix green screen on wsl /linux and ad option to display model axes

[IvanCobotic]

This pull request adresses 2 separate issues,

• Fix for https://github.com/stef-levesque/vscode-3dviewer/issues/32

• Added user setting to display the model axis

I tested on windows 11 and wsl, basic viewer works correctly in my tests.
