Speed up startup

[alexmojaki]

Replacing /full/ with /pyc/ in the CDN URL should load Pyodide faster: https://pyodide.org/en/stable/project/changelog.html#id7

In Pyodide 0.24.0, you can now pass packages to loadPyodide so that you don't have to wait until Pyodide is loaded to download files for loadPackage: https://pyodide.org/en/stable/usage/api/js-api.html#globalThis.loadPyodide . Although that might only help for micropip here.

Nice, not sure what we can do about downloading pydantic-core?

[alexmojaki]

I manually download a URL in parallel to loadPyodide and then unzip it: https://github.com/alexmojaki/pyodide-worker-runner/blob/042118893aab82a896bc37deb10de4c6691f53cf/lib/index.ts#L88-L98

But I don't know if that'll work for stuff that isn't pure Python.
