Sveltefire + Firebase storage

NOTICE

1. Use user.uid instead of user.email for folders (that's how it is in this repo but not how it was in the video)
2. I think this is how the rules should be
   rules_version = '2'; service firebase.storage { match /b/{bucket}/o { match /{folderName}/{allFiles=**} { allow read, write: if request.auth.uid == folderName; } } }
