add realtime kws example for stm32f4xx

realtime KWS using audio from STM32F4xx‘s 12 bit ADC & a microphone. Tested with Seeed Arch Max (STM32F407)

Just a note: the library works well with Arduino IDE 1.6.0, but can't be compiled with v1.0.5.

[get_dominant_freq()](https://github.com/shriphani/Listener/blob/master/VAD.py#L54) returns a frequency (Hz), but it seems better if it just returns the magnitude of most dominant frequency (sqrt Xreal *\* 2 + Ximage *\* 2)
