ds18b20: new module for 1-wire temperature sensor (#3462)
Initial commit of code to support 1-wire (Dallas) sensors such
as the DS18B20. Requires Linux kernel drivers to create a file
in /sysfs which is read by this module, and temperature
typically returned to a temperature_fan.

Note that this sensor is not intended for use with extruders and heater beds, but rather for monitoring ambient temperature (C). These sensors have range up to 125 C, so are usable for e.g. chamber temperature monitoring. They can also function as simple fan/heater controllers. DS18B20 sensors are only supported on the "host mcu", e.g. the Raspberry Pi.
