Improve Color Palette Memory Organization

[Kautenja]

To address 1, the palette data structure was changed from 32-bit to 8-bit. This allows the palette to be stored in RGBA format irrespective of the memory model of the architecture (little-endian vs big-endian). The palette is still accessed as a 32-bit in places for copying entire pixels. This is a sketchy thing to do because the values are actually byte arrays and don't conform to the standard notion of what a uint32_t value should represent. This should be addressed to make the code more clear and less sketchy.

The loops were also replaced with memset and memcpy.

message passing using flags will not work in this case because the frame rate is much slower than the audio rate. The copy to the module is necessary
