Accorindg to the official Arduino library (https://github.com/adafruit/Adafruit_INA219): (In Adafruit_INA219.cpp, line 406-409) Sometimes a sharp load will reset the INA219, which will reset the cal register, meaning CURRENT and POWER will not be available ... avoid this by always setting a cal value even if it's an unfortunate extra step So, I add the re-calibration code into Subfact_ina219.py

According to the official Arduino library (https://github.com/adafruit/Adafruit_INA219),
sometimes the INA219 will be reset because of a sharp load.
To avoid this, add the code that re-calibrates INA219 every time you read the current.
