Pin support unclear

[Spencatro]

Howdy, thank you so so much for your work on this project! I was able to clone the repo and get the main.cpp sample working with a ws2812b strip and my knockoff esp32 devkit in roughly an hour, looking forward to learning how to actually use the library now 😅

I am not sure what pins I can or should use? The default pin used in this example (18) worked great, but the second pin (13) didn't work at all. I tried switching DATA_PIN_1 to a few other values for some additional trial and error and found that the project won't even compile with DATA_PIN_1 set to some values (e.g. 9). Perhaps it's not as simple as just changing that one define?

I found this comment on reddit while falling down a rabbit hole of links from your readme, which seems to suggest there are right and wrong answers, but it's still not clear to me what they are. (Still learning and a lot of this is going over my head tbh.)

Thanks again!
