Improvements to f3d web model url parsing feature

[jo-chemla]

Following PR #1596 and issue #1595
Here is a thread to discuss possible improvements to the model url parsing implementation of f3d web, after some discussion on the f3d discord

Quick notes parsing through the discussion

• parse more url-params like up-vector, widgets, rendering, lighting
• Visual feedback for download (can be done via fetch, more recent browser api than xhr)
• Document feature
• Detect cors and inform user, or any 404

Sidenotes,

• Search query vs hash can be parsed and not necessarily sent to server, that's more standard than hashes
• Bundling, ts module loaded in browser without need to build

Quick PR solving the above listed elements: #1738
