Default sketch won't load due to return type of LedDriver functions

[germede]

Hello!
First of all, thank you for the amazing work and this funny and instructive project.

I was wondering why the Default example wasn't working on my Hexapod anymore.
The sketch loaded successfully, but the robot din't respond anymore and got stuck in some part of the program, as this output shows:

(Missing last "STEMI Hexapod Ryland initialized :)")

After deep debugging I realized that two functions within the LedDriver were causing the problem.
It was difficult to notice because it compiled and loaded well into the hexapod via Arduino IDE.

My Host system is Ubuntu Linux 23.04 and I was using Arduino IDE v2, if that matters.
I'll send you a pull request, if you want to solve this problem globally.
