Several math functions not working on ESP32 #875

I've run into issues using FastLED math functions (lerp8by8, in this particular case) on an ESP32.

This has happened with other functions (n_scale8-related, i believe) in the past but i refactored to get a similar effect without the FastLED math function.

I am unsure exactly what isn't working, but the ESP hangs up entirely once the function is called. no crash, no reboot, just stops. offending code below:

lerp8by8(leds[i].r, targetColor.r, fract);

Where both colors are valid CRGB and fract is 10. I get "before", but not "after".

I've narrowed it down to this using serial monitor, if there is something more i can do to help, i'd be happy to.

Thanks in advance!
