mrzcode.net's Issues

Not working for German ID Cards (TD1) - Fix included

Hi,

this package is not working for German ID Cards (TD1) because the RegEx is partially wrong.
The RegEx for TD1FirstLine should be "([A|C|I][A-Z0-9<]{1})([A-Z<]{3})([A-Z0-9<]{9})([0-9]{1})([A-Z0-9<]{15})" and the RegEx for TD1SecondLine should be "([0-9]{6})([0-9]{1})([M|F|X|<]{1})([0-9]{6})([0-9]{1})([A-Z<]{3})([A-Z0-9<]{11})([0-9]{1})".

The reason is, that for the country string it can be up to 3 Letters, but it can be fewer as well. On German IDs the Country String would be "D<<" and not "DEU". That's why the RegEx has to accept "<" as input as well.
