Implementing registered files in io_uring

Browse Source 
The windows implementation is disabled, currently registering files in
IO Ring when there is inflight IO operations causes corruptions.

Reorganising the code
Improving the scan function
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 cache completely, registred buffers, it supports bashing multiple submissions and can handle multiple files at the same time.
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 cache completely, registered buffers (and registered files in io_uring), 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
fixing the xxh_x86dispatch warnings
Updating the progress printing function
