This pull request, following #329, introduces in the host package :

• A new structure, TemperatureStat, that stores a temperature key and its sensor value. This is to ensure a standard portable structure for temperature sensors data for the package:

type TemperatureStat struct {
	SensorKey   string  `json:"sensorKey"`
	Temperature float64 `json:"sensorTemperature"`
}

• A new function, SensorsTemperatures(), available for the moment on macOS and Linux builds. This function returns a list of TemperatureStat objects - each of these objects represent the value of a temperature sensor.

  • On Linux, the data is obtained the same way as psutil, through the hwmon interface. It is syntaxically correct and follows the psutil's procedure, but hasn't been tested properly yet - if a Linux-using contributor could test this is on their machine, I would be grateful for it.

  • On macOS, the data is obtained through the System Management Controller, with a C library acting as a middleman (host/include/smc.{c,h}). This C library is GNU-licensed, and the license has been kept as-is. Thus, the function is only available for Cgo-enabled builds. Match between a sensor key and what it represents is available in the host/include/smc.h file. The function returns 0 for a sensor value if there was an error on the SMC side or that the sensor is not available, which is the normal behaviour of the SMC function - but if we only want values that could have been accessed, we could ignored sensor values that are equal to 0.

This is my first contribution to the project, so if any contributor has any comment on this, please feel free to speak up!
