ESP32

I believe the the hardware driver on the esp32 (in Arduino IDE) is called differently, not sure about an equivalent function... I think it'll be easier to just directly talk to the module but I got this error on compilation:

SparkFunMLX90614.cpp:284:7: error: 'class TwoWire' has no member named 'end'

I would add, I'm not even calling the function from my code.

I changed line Line 284 - Wire.end(); // stop i2c bus to send wake up request via digital pins
to Wire.endTransmission(true);
That sorted out the issue.

I am seeing a similar problem on an ESP8266 board, perhaps this is similar to this issue

Arduino: 1.8.12 (Windows 10), Board: "SparkFun ESP8266 Thing, 80 MHz, Flash, Legacy (new can return nullptr), All SSL ciphers (most compatible), 512KB (FS:32KB OTA:~230KB), v2 Lower Memory, Disabled, None, Only Sketch, 115200"

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

the change on line Wire.endTransmission(true); worked! thanks
