Feat: Deploy to Fly.io 🚀

[nelsonic]

@LuchoTurtle following on from the great work you've been doing on #2 😍
It's time to deploy this project (and model) to Fly.io

You've been invited to You're admin on the following new org: https://fly.io/dashboard/dwyl-img-class

Todo

• Create a new branch and Pull Request off the initial branch so you don't have to wait for me to review it. 🆕
• deploy the app as imgai or some other short+catchy name that is available on fly.dev 🌹
• ensure that the app has auto-shut-down to conserve resources. Ref: https://fly.io/docs/apps/autostart-stop 📈 📉 👌
  That way we can have a 2GB RAM machine (or whatever you end up needing) and not run it 24/7 wasting cash. 💸 🔥
  • If you need to scale it up and have it always-on so that it's extra fast for a week or two when you're doing "interviews" we can easily do that. 😉
• If prompted to create a Database, go with "Yes" as you will be needing it for the next task: Feat: Store Metadata and Image Classification/Info #3

Thankfully this should be reasonably straightforward as you've already done most of the work to get it all running on localhost and have deployed several apps to Fly.io over the last year.
