Display "invalid PIN ... retry" when PIN in EAC is incorrect (... towards supporting all PIN-states of the German eID-card, see attached picture)
Currently, when the EAC protocol is running and, in conjunction with a basis reader, the PIN is incorrect, no error is displayed an the protocol flow is aborted.
Instead of this behavior, the PIN should be requested again (say for 3 times). The GUI dialog in the PIN capture step should be left open until the PIN is entered correctly, or a PIN entry threshold is reached.

In case of an invalid eID-PIN the number of available retries x is returned in the Response-APDU of GENERAL AUTHENTICATE, which is 63Cx in this case.
See section B.11.2 of https://www.bsi.bund.de/SharedDocs/Downloads/EN/BSI/Publications/TechGuidelines/TR03110/TR-03110_v2.1_P3pdf.pdf?__blob=publicationFile .
The value x must be evaluated and in case of x=2 the user may just enter the PIN again. If x=1 the PIN is suspended and the CAN needs to be entered first.
If x=0 the PIN is already blocked and needs to be reactivated with the PUK. More information about the PIN-management can be found in Section 2.5 of
https://www.bsi.bund.de/SharedDocs/Downloads/EN/BSI/Publications/TechGuidelines/TR03110/TR-03110_v2.1_P2pdf.pdf?__blob=publicationFile and the attached picture.
Note that this information is available in structured form in the CardInfo file and may be used to provide a generic solution.

- Target version changed from 10 to 1.x
The retry issue has been fixed for EAC on a static basis. The next step is to use CardInfos with state tracking to determine the correct action when a PIN is incorrectly entered.
This is a long term goal, so the issue is moved to the long term vision version.
