getStepSize is commented out

[dmrichards26]

In MCP342X.cpp, the following section is commented out by a missing carriage return:

float MCP342X::getStepSize(void) {
uint8_t select = configRegShdw & (MCP342X_SIZE_MASK | MCP342X_GAIN_MASK);
return stepSizeTbl[select];

I beleive this is an accident, and disables that functionality of the library
