Run ./match_data.sh exno.bin where exno.bin is the file written by my patched version of the ExpNo-CARD10-App (see this comment on Schneider's merge request for details).
Currently only data from Austria is used for matching and I can't guarantee that all matches are really found (I tested this with RPIs I created myself to match some of the published diagnosis keys but the used tool has quite a few parameters I don't fully understand :P).
Feel free to clean this up as the code is very hacky at the moment.
