Wire compatibility

Hi, when I compile a sketch with Arduino IDE I receive the following warning:

In file included from ...\Arduino\libraries\SparkFun_MPL3115A2_Altitude_and_Pressure_Sensor_Breakout\src\SparkFunMPL3115A2.cpp:36:0:
...\Arduino15\packages\arduino\hardware\avr\1.8.6\libraries\Wire\src/Wire.h: In member function 'float MPL3115A2::readAltitude()':

             ^~~~~~~~~~~
...\Arduino15\packages\arduino\hardware\avr\1.8.6\libraries\Wire\src/Wire.h:65:13: note: candidate 2: uint8_t TwoWire::requestFrom(uint8_t, uint8_t)
     uint8_t requestFrom(uint8_t, uint8_t);
             ^~~~~~~~~~~

I would like to suggest to change the call requestFrom to use number in uint8_t format. _I2Caddress is already in right format, so second parameter must to be modified.

Example:

if (_i2cPort->requestFrom(_I2Caddress, 3) != 3) { // Request three bytes
   return -999;
}

become

if (_i2cPort->requestFrom(_I2Caddress, 0x03) != 3) { // Request three bytes
   return -999;
}
