ce20bce854 equalizer: Shorten CHUNK_SIZE, partially compensate with HISTORY_SIZE 
CHUNK_SIZE will make the FFT buckets bigger, causing better space usage
by pixels; it will also reduce latency. with original HISTORY_SIZE,
there is too much flicker.

77f6d83bac Change serial speed from 115200 to 57600 
With non-blinkenlight setups, 115200 communication is not reliable at all. About 26kbaud should be enough bandwidth anyway.
