Well this is already starting to grow which imo defeats the purpose of
hardcoding directly on the code so perhaps we could have a section
e.g. [Autopair] where one can enter device names that shall not use
defaults PINs, or may an entry where one can add its own specific PIN
sequence for a given device name including none:

[Autopair]
PIN=0000,1234
# The iCade shouldn't use random PINs like normal keyboards
iCade=
# Nissan Connect carkits use PIN 1234 but it refuses retries
NISSAN CONNECT=1234

With this the logic is check if there is an entry for the device name
and then use as PIN otherwise use the PIN entry (if not defined use
the current settings as default).
