OneWire is now very mature code. No changes other than adding
definitions for newer hardware support are anticipated.
=======
Version 2.3.3 ESP32 Stickbreaker 06MAY2019
Add a #ifdef to isolate ESP32 mods
Version 2.3.1 ESP32 everslick 30APR2018
add IRAM_ATTR attribute to write_bit/read_bit to fix icache miss delay

# OneWire library
A modification of the Arduino OneWire library maintained by @PaulStoffregen. This modifications supports the ESP32 under the Arduino-esp32 Environment.
No changes are required for compatibility with Arduino coding.
Original Source is Paul's 2.3 version. Forked 28DEC2017
@stickbreaker
V2.3.1 30APR2018 add IRAM_ATTR to read_bit() write_bit() to solve ICache miss timing failure.
