Build reproducible JupyterLite site archives inside pyodide kernel

[bollwyvl]

Problem

Building a JupyterLite site still requires a semi-heavy python backend.

Proposed Solution

Create a wrapper kernel that shims enough packages until the Python API equivalent of jupyter lite archive works inside pyodide inside a running JupyterLite site.

This would allow for writing content and delivering a portable site archive directly to contents.

This would be improved, but is not blocked by jupyterlite/jupyterlite#982. This would open the door for other distribution mechanisms (e.g. P2P like webtorrent, git bundle, etc).

Additional context

At present, some things that are kinda broken:

• jupyter(lab)_server would need shimming for contents and translation
• micropip doesn't install data_files Support installing data_files in micropip.install pyodide/micropip#18
  • but, unlike in pip, we probably would know the exact wheel URL they came from, which is almost better
• HTTP fetching
  • some upstreams might not work because of CORS, etc
