Using react-three-fiber for 3d view

[Irev-Dev]

Currently the 3d viewer is part of the CascadeStudio integration, however eventually we're going to want to implement and own it ourselves so that we can add consistency between integration of various packages. when we do so react-three-fiber is a good candidate for keeping in the react ecosystem (though we could used three.js directly)

If we do want to go with react-three-fiber I have a half implementation of trying to set it up to match the style of the CascadeStudio 3d viewer, though of course we can take our own style, either way perhaps the diff might be useful.
(Note the diff is in codersandbox as it was experimenting with that repo at the time)
