The MAX7219 driver has been extended to add support for bitmap drawing on an 8-by-8 LED matrix panel. Consumers can specify the targeted chip, which corresponds to a LED matrix panel, and provide a 64-bit image buffer specifying the pixels which should illuminate.

I extended the `esp-open-rtos/extras/MAX7219` software driver and pushed my changes upstream for merge into the main repository. Until the change is merged, this project will use my fork of the dependency. See [SuperHouse/esp-open-rtos PR #765](SuperHouse/esp-open-rtos#765) for the proposed upstream changes. The forked esp-open-rtos dependency adds software driver support for bitmap drawing to cascaded 8x8 LED Matrix displays using the MAX7219 hardware driver.

Hey @UncleRus 👋🏻 Anything I could do to help get this merged? |

The MAX7219 driver has been extended to add support for bitmap drawing
on an 8-by-8 LED matrix panel. Consumers can specify the targeted chip,
which corresponds to a LED matrix panel, and provide a 64-bit image
buffer specifying the pixels which should illuminate.
The provided example loops a 0-9 digit sequence across a 4 panel 32x8 LED matrix.
