hash_test

Test the speed of Blake3 vs SHA hashes. It hashes a file in the current working directory named test.
To create a 8GB test file, please run the following command:

dd if=/dev/urandom of=test bs=64M count=128 iflag=fullblock

Please note that the conversion function uses 1,000 rather than 1,024 as delimiter between file size units.
