USA flag has wrong shade of red #276

Where: USA color scheme of the SpectrumAnalyzerEffect

Sounds silly, but the red stripes are pinkish. You can verify this by comparing to the red VU pixels in the VU meter, which are a deep rich red.

I'm guessing there's some palette blending going on in the color lookup of the caller to DrawBar, but that's a guess.

I can really only see this easily on a WS2812B matrix - less so on the HUB75

Fixed! I changed it so that we don't do any blending unless the palette is scrolling. When standing still, it does a straight lookup with no blending.
