Exposed call to MRAA SPI frequency for those super long strips where the clock signal will degrade and introduce glitches. Slowing down will fix it without the need for extra filtering or redrivers. Batch mode also helps since only one write per frame will be required.
Added functions that control brightness only for fade effects without the need to keep an extra copy of the pixel color map.
