Extract passport data from WebPage

Today my wife told about an issue about capturing data from a passport.
And then my inner geek said, it has nothing to do with the daily work, so lets do it.

I did like 5 min of googling, 30 min of copy pasting and like 2 hours of bug fixing and I made it:

The pieces are simple.
I needed a cropper. Which I found at https://github.com/fengyuanchen/cropperjs
And I found how to extract the MZR from the passport from: https://github.com/evermeer/PassportScanner/blob/master/Pod/MRZ.swift

I was too lazy to finish implementing the MZR extraction, but it works.
