Openbci_gui: Improve band power widget

[jps2000]

Problem

The chart would look better if the bars are colored
blue, magenta, green, yellow red (left to right)
The response time goes with smooth of the FFT plot ??

Expected

Color the bars blue, magenta, green, yellow red (left to right)
Provide dedicated smoothing adjustment independent of FFT
