feature: add embedded code interpreter using pyodide

[pkarw]

Right now, the code-interpreter tool is dependent on Docker, which is pretty cool as it lets us support a variety of standard languages (extending to typescript, ruby - you name it). However, there's the https://pyodide.org/en/stable/, which lets us launch a Python interpreter inside the node.js process using WebAssembly. At least, it's worth digging in for research.
