Update potree action

The `load_potree_project_from_urlparam.html` has been updated to parse more urlparams, simplified the action by passing a JSON-parseable array of one potree dataset url rather than a complete potree project - which would allow for measurements, volumes, cam pos etc.
Also added a comment to https://potree.org/potree/examples/load_potree_project_from_urlparam.html which should be live once PR is merged by potree maintaining team
