Command line tool for the BLAKE3 hash

 BLAKE3 is a cryptographic hash function that is much faster than MD5, SHA-1,
  SHA-2, SHA-3, and BLAKE2 and
  Secure, unlike MD5 and SHA-1. And secure against length extension.
  Note, This package includes binary "b3sum" which is built from official
  multithreaded implementation of BLAKE3 in rust.
