No temperature output with the example code on Raspberry Pi 3B+

[arctic-alpaca]

Hi,
when running the example code on my raspberry pi, there is no output for components temperature. This seems to be caused by the the get_components() function in src/linux/component.rs. Since /sys/class/hwmon/ exists, /sys/class/thermal/thermal_zone0/temp doesn't get added to the components list and the temperature doesn't get printed by the example code.

I created a pull request which fixed the issue for me #328

anybody: If #827 broke temperature on raspberry-pi feel free to comment here. ;)
