Library for controlling APA102 LEDs through any SPI bus.
This library was created because any other library I found couldn't use any SPI bus other than spi0. As the APA102 LEDs don't have a Chip Select, they have to be on a seperate bus without any other devices attached.
On a Raspberry Pi 4, there are additional SPI busses that can be enabled by appending to /boot/config.txt. For example, to enable SPI5:
enable_uart=0
dtoverlay=spi5-1cs
Here, UART0 has to be disabled, as it shares pins with SPI5.
