* move to separate files mifaresim.[ch] * check CRC of commands * don't execute commands without successfull authentication * ensure correct timing of REQA, WUPA, ANTICOL and SELECT responses * trace reader commands immediately, only fix start time after tag response. Decreases time to be ready for next reader command. * remove iso14443-4 remnants * trace raw reader commands instead of decrypted ones * some refactoring * fix hf mf sim * timing: decrease time to get ready for new reader commands
