[solved] Atmelavr outdated libraries

After some research I found, that the libs in the avr toolchain of platformIO are outdated

PlatformIO does have the newer toolchain, it’s just not set as default.

Per Fastled clockless_trinket.h:326:24: error - #6 by maxgerhardt you can add

platform_packages =
  ; use GCC AVR 7.3.0+
  toolchain-atmelavr@>=1.70300.0

to the platformio.ini and get the 7.3.0 toolchain instead of the 5.4.0 one.
