Filter APDUs in log output

Description

For remote debugging it is often necessary to ask a user for a logfile from scdaemon. Although we filter most sensitive information out in log files, this is not the case for --debug cardio and --debug-ccid-driver. In particular it is possible to view the PIN of a user during a VERIFY or CHANGE REFERENCE DATA.

We should filter those APDUs as well and hide the actual PIN by default.

We need to do this also for CHANGE REFERENCE DATA - however, there should be an extra option so that we can debug this despite of the redacting.
