[jqdq]

Description

This pull request sets up web app deployment to the crossword generator project using Pyodide and Webpack. We have also connected Supabase via the JavaScript Pyodide API. With this change, we will be able to deploy the crossword generator as a web app and use Python code to generate crossword puzzles in the browser.

Changes Made

• Added webpack.config.js file to bundle the JavaScript and Python code
• Added index.html file to serve as the entry point for the web app
• Added index.js file with functions to generate crossword puzzles using Pyodide
• Added loadpy.js file to load Pyodide in the browser
• Registered supabase4js module with Pyodide
• Connected Supabase via the JavaScript Pyodide API
• Added example usage of Pyodide in index.js
• Added exclusive package containing libraries dependant on the runtime.

Testing

• Tested the web app deployment by running the bundled code in a local server
• Verified that the crossword puzzles generated by the web app are correct

I autogenerated this lmao

I want to note that tests pass on desktop, and GitHub actions runner needs #25 to be finished in order to work.
