Implement driver for SPH0645 #13

STM32 ADC peripheral only has 12 bit resolution which probably isn't making the most out of the MAX9814 microphone. In lieu of buying a dedicated ADC, implement driver for SPH0645 MEMS microphone and see how performance on that compares. Has 18 bit resolution so hopefully results will be better.
