Also scan ID card and compare data to that from vaccination certificate

[RaphaelWimmer]

General Idea:

• require the user to put the ID card in front of the camera
• identify card dimensions, rotate image accordingly
• find photo location via Haar cascades, find photo edges, extract photo
• find good threshold value to distinguish text from background
• apply threshold and do OCR via pytesseract
• identify name, date of birth fields via templates for accepted ID cards or automatically
• check whether name and DOB are the same for vaccination certificate and ID card

Optional:

• If the vaccination certificate has been scanned before the ID card, we already have a name and DOB that we expect to find on the ID card. Therefore we could use this information (template matching?) to facilitate the check.
