Missing reporting

1. Grab your xlsx
2. Unzip it
3. Open xl/worksheets/sheet1.xml from unzipped folder
4. Beatify it (optional if you want to suffer 😉)
5. Visualise table inside using s parameter of cell (e.g. 1 - black, 2-5 - white)
6. You got QR ✨

Provided script.py can unzip xlsx, parse xml and generate qr as html table.
