Some things I'd like to try in this repo

• rust
• image comparison
• concurrency / parallelism if appropriate

If wishing to PR:

• ensure you've installed cargo-make:
  • cargo install cargo-make
  • run the install task
    • cargo make install

Not intending to handle

• responding to there being mismatched images, caller of cli should see result file and decide what they want to do
• terminal interaction by user
  • should just take starting input and run
