This code allows Wire.begin() to assign the default values of SDA, and SCL only if they have not been previously configured. Arduino libraries that use Wire() usually re-init the I2C interface in their initialization code with a call to Wire.begin(). If a user app sets custom pins assignment in setup(); These assignments will be overwritten with the default values whenever Wire.begin() is called.
