Description

Adds support for DS18B20 one wire temperature sensors. The default setting assumes a single sensor and does not require the user to go and find the address.
The optional one_wire_ID parameter is for the available for muliptle sensors (ie: one outside, one in the greenhouse, etc) but does require a lookup of the address. The docs include the
location and format of the address. This was tested on a Raspberry Pi 3 for about a year in a small cheap greenhouse where is got down to single digit temperature and over 100 in the summer
with fine performance, minus the occasional restart when the Pi likely was overheating.
