issue with compiling with Adafruit_MLX90393.cpp

[Myzhencai]

Hi ,@dychen24, thanks for sharing this awsome work:-) As you can see, we build the PCB board and we want to make it work ,when we fllowed the instruction of the web: https://learn.adafruit.com/bluefruit-nrf52-feather-learning-guide/arduino-bsp-setup and we replaced the liabary of Adafruit_MLX90393(version2.0.0) with your Codes it seems when we compiled with this staff ,it come out with the fllowing errors : can you help with us :-) ,hava a nice day :-)

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

by the way this is the pcb board we did as per the opensource file
