Officially brought to web!

I had to wrestle with PyScript for an incredibly long time, but it’s finally running smoothly!

Two big changes to the code are:

1. micropython support, which runs and loads SO much faster than Pyodide (but meant I had to rewrite itertools.product and np.linalg.solve)
2. helper classes to create a mechanical system and create energy formulae, which abstracts the math away into much more of an intuitive system!

The code for setting up the system gets simpler and simpler each time…
