Tweaks for fan service to keep it offline more frequently and scale up faster ; wil adjust polling interval after further testing and verification
Replace pimoroni fan shim
Replaced with argon fan ; will be adding fan speed based on temp to piframe-go soon

Closing / wontfix as this is well outside the scope of PiFrame. Moved to a personal project instead.
