extmod/modonewire.c: Add "modonewire" from Genuine MicroPython
This tremendously improves robustness of 1-Wire support. While the original Pycom implementation is written in pure-Python, this adds the C-level "modonewire" module from Genuine MicroPython. It will also perform crc checks when reading the DS18B20 sensors. Driver support by @robert-hh: https://github.com/robert-hh/Onewire_DS18X20
