I have added a pre-configured version of the ws2812b i2s library to the
Arduino code. This removes the need to download and install the ws2812b
i2s library manually. The ws2812b code has been preconfigured to reduce
the temporal compared to the default value. The default value was found
to cause excessive flickering. The readme has been updated to reflect
this change. Also added a note about the maximum number of LEDs (255)
* Moved all module settings to a new config.py file
* Completely overhauled visualize.py and added a new radiate effect that
colours the radiative beats according the beat frequency.
* Improved some constants like the decay constant to be parametric so
that they scale to any led strip size
* Added temporal dithering to Beat.update_pixels() so that it now
supports fractional speed values. Being limited to integral values was
starting to become a problem.
* Overhauled and simplified the LED module.
* When updating pixels, the LED module no longer sends UDP packets for
pixels that have not changed. This optimization reduces the packet load
significantly and should allow for higher refresh rates.
* Renamed lookup_table.npy to gamm_table.npy to better reflect that the
table is used for gamma correction of the LED strip
