The windows implementation is disabled, currently registering files in
IO Ring when there is inflight IO operations causes corruptions.
Implementing a config file.
Some code cleanup
The IO Ring now 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
