added to main esp32 arduino issues

[david-nc]

The warning with requestFrom() is caused by passing a bool instead of a uint8_t as the third argument to the function.
Correction would be to change line 112 in Adafruit_HMC5883_U.cpp from
Wire.requestFrom((byte)HMC5883_ADDRESS_MAG, (byte)6, true);
to
Wire.requestFrom((byte)HMC5883_ADDRESS_MAG, (byte)6, (byte)true);
