Only Compiles with ESP 32 2.x

[BrookeDot]

This is an amazing Library, my favorite of making DMX easy for Arduino/ESP32. However, one must use ESP32 2.x.x to have it compile (currently 2.0.17). UIsing the newer 3.x (currently 3.1.3) will fail with the following error:

I spent some time looking into the "why" here but never got to the bottom of it, but reporting here if someone else come across it and want to dig in, or work around this problem.
