I've just realised I could probably do this in a single 32-bit word, auto-pull every 24 shifted bits and configure the data-mover DMA to not increment its read address and then the need for the control DMA channel goes away. Still, I'd like to know a cleaner solution to the pointer to address of pointer to address problem.
Edit: Or maybe the control DMA channel is still needed, to ping-pong via `chain_to`, but it doesn't need to actually transfer anything?
