Create simple PyScript page showing 2022 crimes data

[RandomFractals]

• Use slim 2022 crimes data created in #29
• Add some charts from our old Jupyter notebook, but use Altair charting lib instead:

Starter page for now: https://github.com/RandomFractals/chicago-crimes/blob/main/apps/pyscript/index.html
