If I'm going to eventually have it work offline as a PWA:

• Turn this into an offline enabled PWA #26

The first step is going to be having it work based entirely on files in this repository - with no external HTTP requests made at all.

I need that for both Pyodide and its WASM build as well as all of the Python wheels that Datasette Lite needs to install using micropip.

I think I've figured out how to do it: https://pyodide.org/en/stable/usage/loading-packages.html#installing-wheels-from-arbitrary-urls

Pure Python wheels can also be installed from any URL with micropip,

import micropip
micropip.install(
    'https://example.com/files/snowballstemmer-2.0.0-py2.py3-none-any.whl'
)

Micropip decides whether a file is a URL based on whether it ends in ".whl" or not.
