I tried to port stm32h7xx-hal's SAI implementation to this HAL. It is no tested yet but I plan to use it in one of my projects.
DMA is missing for the moment as this HAL's implementation is quite different from stm32h7xx-hal's.
I took the SPI DMA implementation as inspiration but ended in macro hell. Hopefully I can come up with something as in my opinion DMA is mandatory for audio stuff.
