Looking for a way to expand the number of strips available when constrained on free GPIO pins.

Describe the solution you'd like
Creating an ESP32 I2S driver to enable multiple outputs over a single pin through a shift register as described in this article:
https://hackaday.com/2019/05/07/lots-of-blinky-esp32-drives-20000-ws2812-leds/

Describe alternatives you've considered
I am unaware of any other options to achieve multiple strips running off of a single data pin.

Additional context
I'm unfamiliar with this codebase and I2S driver implementation in general, but I'm currently trying to understand both and would be willing to help in some capacity.
