Offline + 3rd Party Ability

[WebReflection]

Breaking Change

While nobody should be affected by the new structure, whoever was pointing at CDNs and their .../core.js entry should now switch to .../dist/index.js instead.

This MR addresses the following topics:

• all lazy loaded 3rd party dependencies are now available through the dist/* folder like we do in PyScript
• the Worker blob has been orchestrated to re-resolve at runtime via import.meta.url lazy dependencies to be able to use the same dist folder for everything
• both the toml and the zip library, not used but needed soon, can be now reached through the CDN so we also don't depend on third party CDNs to provide our own content
• all exports have been updated

TODO I need to be sure current structure does not break anything in PyScript.
