Port the getCRGBForBand palette generation logic from the upstream WLED usermods/audioreactive fork, adding an opt-in 'add-palettes' setting that registers three audio-reactive color palettes with the core palette system and refreshes them each loop.
Ports upstream WLED PR #5467: adds two new audio-reactive palettes derived from a slowly-smoothed (~390ms EMA) per-band average, using spectral centroid and bass/mid/high energy ratio to drive hue/saturation.
