FInd DUPlicates (or Find fIle DUPlicates)

A simple utility in Rust which helps to find duplicates. Uses blake3 (currently) hashing.

It's an Initial version. Here is what I would like to add to it:

• Refactor: get rid of .unwrap()
• Refactor: use proper error propagation and handling: ? and thiserror
• Refactor: get rid of .clone()
• Use different hashing algorithms to be able to play with them (to measure theirs speed on my non-test data) (sha256, blake2x, ...)
• use clap
  • command line arguments
    • --show-all
    • --show-only-duplicates
    • --show-hashes
    • --delete
    • --delete-without-asking
    • --block-size
  • version
  • author
  • help/usage
• run in the current directory by default (no need to pass the path)
• hash a single file, if it's file or traverse the directories (currently all the args are treated as directories).
• statistics
  • speed of the hashing
  • total number of processed bytes
  • total time
  • time to hash 1Kb/1Mb/1Gb of data
