Based on qm's example code at https://github.com/qm210/ledder-to-heaven

To run:

- Adjust wled_host and wled_port in udp_sending.py
  (sorry, don't know how to python)

- python3 udp_sending.py

- Adjust "await asyncio.sleep(0.1)" if it's too fast, I guess...
  (no time for hardware testing...)

Didn't manage to produce a small executable for this effect in time, so
we're dumping prerendered frame data.
