+5.0: Implementing the IO Ring for windows and ui_uring for linux instead of buffered hashing, huge performance gains. The IO Ring is event driven, thread local, uses DMA and direct disk I/O, bypassing the OS cash completely, registred buffers, it supports bashing multiple submissions and can handle multiple files at the same time.
 Hashing small files using XXH3_128bits() instead of the streaming pipeline(XXH3_128bits_reset(), XXH3_128bits_update(), XXH3_128bits_digest()), this reduses the overhead of creating a state and digest, coupled with the IO Ring it improves the hashing of small files whose size is inferior to the size of IO Ring buffers
