Temporarily update lib/esp-open-rtos dependency to use forked version

trentrand · trentrand · commit 4e47784b2e65 · 2020-11-29T16:30:57.000-05:00
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.
