MRZ Improvement

[nicholemnl]

Current Behavior

Currently MRZ scan does not work sometimes. It works fast on some cards and others it will not.

Upon investigation, we found out that the cropped scanned image is not accurate enough and cuts off the MRZ code makes it harder to decode it.

Expected Behaviour

1. Create a bounding box as a guide for the user to focus on the MRZ code
2. Fast scanning
3. Accurate as much as possible
4. API for the bounding box guide so it can be use in other APP

Context

This happens even in the release version

• Version: 0.4.5-beta

After initial test build, a few bugs created :

• App crashes after scanning with e-Passport
• MRZ Scan does not work with real passport
• MRZ Scan still does not give accurate result
• MRZ Scan still takes time to scan cards
