Wire.beginTransmission and Wire.endTransmission should not be used together with Wire.requestFrom.

In the file "MHML/hardware/src/max30102.cpp", the Wire.requestFrom() has a Wire.beginTransmission() before it and a Wire.endTransmission() after it. Those Wire.beginTransmission() and Wire.endTransmission() may be removed.
